Also located within the pelvis are the vagina, uterus, and paired oviducts, or fallopian tubes, in which eggs are conveyed from the ovaries to the uterus. MALE In a man, the testes, which produce sperm and sex hormones, hang well outside the pelvis, in the scrotum. The rest of the male reproductive system consists of a pair of tubes called the vasa deferentia singular, vas deferens , the accessory sex glands the seminal vesicles and the prostate , and the urethra. Lactiferous duct A series of 15 to 20 ducts each drain a lobe of the breast.

Nipple Lactiferous ducts open on highest point apex of the nipple, which extends from center of the breast. Secretory lobule containing alveoli One of several small compartments housed within each lobe of the breast. A lobule is composed of grapelike clusters of milk-secreting glands called alveoli. Fimbriae Fingerlike Ovary projections that Female gonad; is form a feathery end hidden away, deep to each oviduct within the pelvis.

Shaft of penis Cervix of uterus Formed by masses of erectile The cervix, or neck of the tissue, which become engorged uterus, projects down into with blood during erection the vagina. Urethra Conveys sperm and Vagina urine through penis Flexible muscular tube that accommodates the male Epididymis penis during coitus; during A much-coiled tube on the childbirth, it expands to allow back of the testis; sperm are the fetus to pass through stored and mature here.

Testis Male gonad; hangs outside body cavity, in the scrotum. Four pea-sized glands at the Part of the brain, lying under. Parathyroid gland including melatonin. Pituitary gland Hypothalamus. Thyroid gland Pineal gland. The autonomic nervous system uses nerve impulses and neurotransmitters to send information in a swift and localized way. The glands of the endocrine system produce hormones—chemical messengers, often carried in the blood—that act in a slower, more prolonged, and more generalized way.

The pituitary gland produces hormones that affect other FRONT endocrine glands, which sometimes form discrete organs. There are also hormone-producing cells in the tissues of many other organs. Adrenal gland Pancreas A pair of glands, also known Has cells that produce hormones as suprarenal glands, that controlling glucose metabolism: Ovary Ovaries produce sex hormones as well as gametes reproductive cells called ova.

The Anatomy Atlas splits the body into seven regions, starting with the head and neck and working down to the lower leg and foot.

MRI scans at the end of each section show a series of real-life images through the body. Frontal bone Parietal bones. TOP Paired bones forming most Coronal suture. In a young adult skull, the sutures are. The mandible of a In addition to the main bones labeled on these The skull comprises the cranium and mandible. The joint fuses during early infancy, pages, there are sometimes extra bones along the The cranium itself comprises more than 20 bones attachment for the muscles of the head and neck.

Glabella Area between the two superciliary arches; glabella comes from the Latin for smooth, and refers to the bare area between the eyebrows. Mental foramen Hole that transmits branches of the mandibular nerve; mental can refer to the chin mentum in Latin. The hyoid bone is also vertebra, which supports the skull, is called the the posterior, mastoid part of the cranium at the. In this side view, we can also see more of the.

This small bone is a very important anchor Frontal bone.

Nodding movements of the head occur The cervical spine includes seven vertebrae, the top jaw joint. Greater wing of sphenoid bone. Lacrimal bone Takes its name from the Latin for tear; tears drain from the surface of the eye into the nasolacrimal duct, which lies in a groove in this bone. Nasal bone. Zygomatic bone From the Greek for yoke; it forms a link between the bones of the face and the side of the skull Occipital bone.

Angle of mandible Where the body of the Mental foramen mandible turns a corner to become the ramus. Superior nuchal line Occipital bone The trapezius and sternocleidomastoid muscles attach to this ridge External occipital protuberance Inferior nuchal line Slight ridge lying between the attachments of some of the deeper neck muscles Foramen magnum.

In the middle, there is one large hole—the foramen magnum—through which the brain stem emerges to become the. But there are also many smaller holes, most of them paired. Through these holes, the cranial nerves from the brain escape to supply the muscles, skin, and mucosa, and the glands of the head and neck.

Blood vessels also pass through some holes, on their way to and from the brain. At the front, we can also see the upper teeth sitting in their sockets in the maxillae, and the bony, hard palate. Hypoglossal canal Mastoid foramen The hypoglossal nerve, An emissary valveless supplying the tongue vein passes out muscles, exits here through this hole Internal acoustic meatus The facial and Jugular foramen vestibulocochlear nerves The internal jugular vein pass through this hole and the glossopharyngeal, vagus, and accessory nerves emerge from this hole Basiocciput Part of the occipital bone, in front of the foramen magnum, Petrous part of that fuses with the body of the temporal bone sphenoid bone Foramen lacerum Foramen spinosum Entry point of the middle meningeal artery, which Foramen ovale supplies the dura mater and the bones of the skull Pituitary fossa.

Foramen rotundum Lesser wing of sphenoid bone The maxillary division of the trigeminal nerve passes through this round hole Optic canal Orbital part of Cribriform plate of ethmoid frontal bone Area of the ethmoid bone Part of the frontal bone pierced by holes, through that forms the roof of which the olfactory nerves the orbit, and also the pass. Some of those blood vessels leave deep grooves on the inner surface of the skull: We can also see that the skull bones are not solid, but contain trabecular bone or diploe , which itself contains red marrow.

Some skull bones also contain air spaces, like the sphenoidal sinus visible here. We can also appreciate the large size of the nasal cavity, hidden away inside the skull. Frontal bone Forms the anterior cranial fossa, where the frontal lobes of the brain lie, inside the skull. Frontal sinus One of the paranasal air sinuses that drain into the nasal cavity, this is an air space within the frontal bone. Pituitary fossa Fossa is the Latin word for ditch; the pituitary gland occupies this small cavity on the upper surface of the sphenoid bone.

Superior nasal concha Part of the ethmoid bone, which forms the roof and upper sides of the nasal cavity. Sphenoidal sinus Another paranasal air sinus; it lies within the body of the sphenoid bone. Middle nasal concha Like the superior nasal concha, this is also part of the ethmoid bone.

Inferior nasal concha A separate bone, attached to the inner surface of the maxilla; the conchae increase the surface area of the nasal cavity. Palatine bone Joins to the maxillae and forms the back of the hard palate. Grooves for arteries Meningeal arteries branch on the inside of the skull and leave grooves on the bones. Internal acoustic meatus Hole in petrous part of the temporal bone that transmits both the facial and vestibulocochlear nerves.

External occipital protuberance Projection from occipital bone that gives attachment to the nuchal ligament of the neck; much more pronounced in men than in women. Hypoglossal canal Hole through occipital bone, in the cranial base, that transmits the hypoglossal nerve supplying the tongue muscles. The extremely dense petrous parts of the temporal bones contain and protect the delicate workings of the ear, including the tiny ossicles malleus, incus, and stapes that transmit vibrations from the eardrum to the inner ear.

With the opposite maxilla forms the parietal bones at Forms the front Frontal bone. Occipital bone Occipital bone Forms the lower part of the back of the skull. Zygomatic bone Cheek bone, also lateral border of the eye socket. Petrous part of temporal bone. Orbital plate of ethmoid bone.

The muscles of the face have very important Acromion of. The wrinkles and creases lie faces—our eyes, noses, and mouths. But they also. It is these muscles that allow. As we age, and our skin forms creases and noses in distaste, to smile gently or grin widely, and. They open and close the apertures in our. Levator labii superioris Raises the upper lip.

Latin for circular. Literally, lifter of In Latin, lifter of alaeque nasi Levator labii. Levator labii and the wing the upper lip. In this side view, we can see the two largest muscles of mastication, the temporalis and masseter muscles. Two smaller muscles attach to the inner surface of the mandible. This makes the entire scalp movable on the skull. Epicranial aponeurosis Temporalis Attaches from the temporal bone of the skull to the coronoid process of the mandible jawbone Occipital belly of occipitofrontalis.

Posterior belly of digastric The digastric pulls the mandible upper jaw bone down to open the mouth, and pulls the hyoid bone up in swallowing. Thyrohyoid Attaches from the hyoid bone to the thyroid cartilage of the larynx.

Superior belly of omohyoid Omo comes from the Greek for shoulder; this muscle is named after its attachments—from the hyoid bone to the shoulder blade.

Sternohyoid Attaches from the sternum to the hyoid bone. Sternothyroid Attaches from the sternum to the thyroid cartilage. Soft palate A pair of muscles sweep down from the base of the skull on either side, into the soft palate; two others leave the palate and run down into the tongue and the pharynx. Palatoglossal fold Genioglossus Attaches from the inside of the mandible and sweeps up into Palatine tonsil the tongue Palatopharyngeal fold Hard palate.

Epiglottis One of the cartilages of the larynx; it helps protect the laryngeal inlet during swallowing. Pharyngeal raphe process into the pharynx.

The tongue is a great mass of a sphincter just before the Inferior constrictor start of the esophagus that muscle, covered in mucosa. Some of its muscles arise from the hyoid bone and the of the pharynx stops you from mandible, and anchor it to these bones and move it around.

The pharyngeal muscles are important larynx as you breathe in swallowing, and the laryngeal muscles control the vocal cords. The muscles that Longitudinal muscle Circular muscle of move the eye can be seen on p. Sternocleidomastoid Connecting the Glottis mastoid process of The gap between the the skull above to the vocal cords; muscles clavicle and sternum of the larynx act to below, this muscle turns change the position the head to the side and tension of the vocal cords Anterior scalene.

Trapezius Subcutaneous fat. The human brain has grown larger and larger over the course of evolution, and it is now so overblown that the frontal lobes of the brain lie right over the top of the orbits that contain the eyes.

Think about any other mammal, perhaps a dog or a cat for easy Middle frontal gyrus reference, and you will quickly realize what an odd shape the human head is—and most of that is a result of our huge brains.

Looking at a side view of the brain, you can see all the lobes that make up each cerebral hemisphere: Tucked under the cerebral hemispheres at the back of the brain is the cerebellum Latin for little brain. The brain stem leads down, through the foramen magnum of the skull, to the spinal cord. Olfactory bulb. Optic nerve The second cranial nerve. Central Parietal sulcus lobe. Frontal lobe Parieto-occipital sulcus.

Precentral gyrus The location of the primary motor cortex—where nerve impulses that lead to muscle movement originate. Precentral sulcus Divides off the precentral gyrus from the rest of the frontal lobe. Central sulcus The division between the frontal and parietal lobes. Postcentral gyrus Lies just behind the central sulcus. The primary somatosensory cortex, which receives sensory information from all over the body. Postcentral sulcus Separates the postcentral gyrus from the rest of the parietal lobe.

Lateral sulcus A deep cleft dividing the frontal and parietal lobes from the temporal lobe below. Superior temporal gyrus Includes the primary auditory cortex, where sensory information related to hearing is received. Superior temporal sulcus Sulcus is a Latin word meaning groove or furrow. Inferior temporal Cerebellum sulcus Sits under the occipital lobes at the back of the brain; responsible for coordinating movement and managing balance and posture Pons Derived from Latin for Medulla oblongata bridge, this is the part The lowest part of the brain of the brain stem stem; it continues down to between the midbrain form the spinal cord.

To the naked eye,. It looks rather like a large, pinkish gray, wrinkled walnut— there is little to suggest that the brain is the most complicated organ in the human body. Its true. The outer complexity is only visible through a microscope, layer of gray matter, called the cortex, is highly revealing billions of neurons that connect with folded.

Underneath the brain we see some more each other to form the pathways that carry our detail, including some of the cranial nerves that senses, govern our actions, and create our minds.

Middle frontal gyrus Inferior frontal sulcus. Inferior frontal gyrus Superior frontal gyrus. Cingulate sulcus Precentral gyrus. Postcentral gyrus Superior parietal lobule. Intraparietal sulcus Divides the superior from the Central sulcus inferior parietal lobule. This gyrus, Turns a corner around the end on the left, has been of the superior temporal sulcus. Inferior parietal lobule Postcentral sulcus Parieto-occipital sulcus Divides the parietal and occipital lobes.

Frontal pole Olfactory bulb. Olfactory tract Lateral sulcus. Temporal pole. Optic chiasma Where the optic nerves partially cross each other Pituitary gland Pons. This division is clearly seen when viewing the brain from the front, back, or top. Areas of the brain that receive and process certain types of information, or govern movements, can be very widely separated. The visual pathways from the eyes end in the cortex of the occipital lobe at the back of the brain, and visual information is also processed in this lobe.

Fissures The grooves in the cerebellum. Folia The bulges in Occipital pole the cerebellum. Hypothalamus Plays an important role in regulating the internal environment of the body, by keeping a check on body temperature, blood pressure, and blood sugar level, for instance. Pituitary gland Produces many hormones and forms a link between the brain and endocrine system. Mammillary body Part of the limbic system of the brain.

Dura mater Outer layer of the meninges; dura mater is Latin for hard mother. Septum Caudate. Superior sagittal sinus pellucidum. The 12 pairs of cranial nerves the standard of cranial nerves emerge from the brain stem.

This has. A few also contain autonomic branches in the neck, but then continues on to supply organs in the thorax and right down in the abdomen.

The olfactory nerve and the optic taste, and so on, can help doctors pinpoint nerve attach to the brain itself. The other 10 pairs neurological problems in the head and neck. Olfactory bulbs Receive the olfactory nerves CN1. Olfactory tracts Pons. Hypoglossal nerve CN XII Vagus nerve CN X Formed from a series of rootlets Exits the cranium via the emerging from the groove jugular foramen, along between the olive and pyramid with the glossopharyngeal of the medulla and accessory nerves.

Glossopharyngeal nerve CN IX. Sclera Iris Upper eyelid. EYE Lacrimal caruncle. The eyes are precious organs. They are well protected inside the eye sockets, or Lacrimal papilla bony orbits, of the skull.

They are also protected by the eyelids, and bathed in tears produced by the lacrimal glands. Each eyeball is only 1 in 2. Other nerves supply the eye muscles and the lacrimal glands, and even continue on to the face to supply sensation to the skin of the eyelids and forehead.

Conjunctiva Sclera Lateral rectus Thin mucous membrane From the Greek for muscle covering the front of the hard; the tough, outer eyeball, as well as the inner coat of the eyeball surfaces of the eyelids, but not the cornea Choroid This layer is packed Iris with blood vessels From the Greek for rainbow; contains smooth muscle: Temporal bone Forms part of the side wall and Malleus base of the skull; This mallet-shaped ossicle houses the attaches to the back of the workings of tympanic membrane and the ear connects to the incus.

External acoustic meatus The outer third of this canal is made of cartilage, while the inner two-thirds is a channel within the temporal bone; the meatus is lined with thin skin, which continues on to the eardrum. Tympanic membrane The eardrum vibrates as sound waves buffet it; the ossicles the malleus, incus, and stapes carry those vibrations through the. HEAD middle ear to the inner ear.

The middle ear is an air space inside the temporal bone. It contains the ossicles ear bones and is linked to the pharynx by the pharyngotympanic, or eustachian, tube. Similar hair cells in the vestibular apparatus the semicircular canals, utricle, and saccule convert mechanical stimuli, produced by motions of the head, into nerve impulses see pp. The sensory nerves leaving the inner ear join to form the vestibulocochlear nerve.

Second cervical nerve C2 Along with C3 and C4, this nerve supplies sensation to the skin of the neck as well as supplying a range of muscles in the neck. Third cervical nerve C3. Fourth cervical nerve C4. The last four cranial nerves all appear in the neck. The glossopharyngeal nerve supplies. The vagus nerve is sandwiched between the common carotid artery and the internal jugular vein,.

The accessory nerve supplies the sternocleidomastoid and trapezius muscles in the neck, while the last cranial nerve, the hypoglossal, dips down below the mandible, then curves back up to supply the muscles of the tongue.

We can also see spinal nerves in the neck. The upper four cervical nerves supply neck muscles and skin, while the lower four contribute to the brachial plexus and are destined for the arm.

Inferior meatus The nasolacrimal duct— draining tears from the inner corner of the eye—opens into the nasal cavity here; that is why your nose tends to run when you cry Cut edge of inferior concha. Nasopharynx Uppermost part of the Nostril pharynx, behind the nasal cavity—which ends level with the back of the hard palate—and above the oropharynx.

Laryngopharynx Lower part of the pharynx, behind the larynx. False vocal cord Cricoid Also known as the cartilage vestibular cord. Thyroid Trachea cartilage. Ethmoid Frontal sinus sinus. Here the air is cleaned, warmed, and moistened before its onward journey. The nasal cavities are divided by the thin partition of the nasal septum, which is composed of plates of cartilage and bone.

The nasal cavity is lined with mucosa, which produces mucus. This often undervalued substance does an important job of trapping particles and moistening the air. Below and in front of the pharynx is the larynx—the organ of speech. The way that air passes through this can be modulated to produce sound. Hyoid bone Epiglottis Elastic piece of cartilage named after the Greek for upon the tongue; it sits behind the tongue, and helps protect the airway during swallowing.

The vertebral artery runs up through holes in the cervical vertebrae and eventually enters the skull through the foramen magnum. The common.

Veins of the head and neck come together like river tributaries, draining into the large internal jugular vein, behind the sternocleidomastoid muscle, and into the subclavian vein, low in the neck.

Posterior communicating artery. Posterior The brain has a rich blood supply, cerebral artery which arrives via the internal carotid and vertebral arteries. The vertebral Basilar artery arteries join together to form the basilar artery. The internal carotid Internal carotid arteries and basilar artery join on artery the undersurface of the brain to form the Circle of Willis. From there, three pairs of cerebral arteries make External carotid their way into the brain.

The veins artery of the brain and the skull drain into Vertebral venous sinuses, which are enclosed arteries within the dura mater the Travel up through the foramina outermost layer of the meninges in the cervical and form grooves on the inner vertebrae, and enter the skull surface of the skull.

Canine First premolar Around 11 years Around 9 years. First molar Second premolar Around 6 years Around 10 years. Second molar Enamel Around 12 years The hardest tissue in the human body. There is overlap between these two systems, and their functions are integrated and controlled within the hypothalamus of the brain.

The pituitary gland has two lobes; its posterior lobe develops as a direct extension of the hypothalamus see pp. Both lobes of the pituitary gland secrete hormones into the bloodstream, in response to nerve signals or blood-borne releasing factors from the hypothalamus. Many of the pituitary hormones act on other endocrine glands, including the thyroid gland in the neck, the suprarenal glands on top of the kidneys, and the ovaries or testes.

Pituitary gland tissue Some hormone-secreting cells in the anterior pituitary appear stained red in this image, including those that produce growth hormone, others are stained blue. Pineal gland.

The discovery of X-rays at the end of the 19th century 4 suddenly created the possibility of looking inside the human body—without having to physically cut it open. Medical imaging is now an important 5 diagnostic tool, as well as being used for the study of normal anatomy and physiology.

In computed tomography CT , X-rays are used to produce virtual sections or slices through the body. MRI is very useful for 2 Larynx looking in detail at soft tissue, for instance, muscle, tendons, and the brain. Also seen clearly in these sections are the eyes 1 and 3 , the tongue 1 and 2 , the larynx, vertebrae, and spinal cord 2 and 5.

Eighth to tenth ribs The costal cartilages of these ribs each attach to the costal cartilage above.

Manubrium sterni The sternum is shaped like a dagger or short sword; manubrium means handle or hilt in Latin. Body of sternum Sternum comes from the Greek for breastbone.

Xiphoid process The tip of the sternum takes its name from the Greek word for sword. It not only acts as an anchor for muscle attachment, but during breathing the ribs also move up and out to increase the volume inside the thoracic cavity and draw air into the lungs.

It also forms a protective cage around the precious organs inside: The bony thorax includes the 12 thoracic vertebrae, 12 pairs of ribs and costal cartilages, and the breastbone, or sternum. The upper seven ribs all articulate with the sternum via their costal cartilages. The eighth to the tenth costal cartilages each join to the cartilage above, creating the sweeping curve of the ribcage below the sternum on ANTERIOR each side.

Twelfth rib The twelfth rib is even shorter than the eleventh, and tucked underneath muscles, so it cannot be felt. There are cartilaginous joints between the vertebrae at the back of the thorax, and between the parts of the sternum at the front.

The joints between the ribs and the vertebrae at the back are synovial, allowing the ribs to move during breathing.

It's really well done. In addition, there's a user controlled Head to Toe Body Scan, which allows the user to look at particular areas of interest. There's also a couple of annotated MRIs that are quite interesting. My one complaint is that the book is quite heavy and a little hard to hang on to for long reading sessions. I really don't want to give up the book's generous size, which allows for large photographs, so I guess I'll have to prop it up or use a table to hold the book.
