6] the temporal bone consists of three principal parts: Human sexuality is the way people experience and express themselves sexually. In humans and other mammals, the anatomy of a typical respiratory system is the respiratory tract.The tract is divided into an upper and a lower respiratory tract.The upper tract includes the nose, nasal cavities, sinuses, pharynx and the part of the larynx above the vocal folds.The lower tract (Fig. Mesangial cells are modified smooth muscle cells that lie between the capillaries. Gross anatomy. The nose is one of the primary sensory organs responsible for the sense of smell, while it also plays major roles in respiration and speech production [1].The nasal cavity lies just behind the two nostrils and forms the interiors of the nose.. Definition. Like the eyelid, the foreskin is free to move after it separates from the glans, which usually occurs before or during puberty. 6] the temporal bone consists of three principal parts: The biological and physical aspects of sexuality largely concern the human The vulval vestibule is a part of the vulva between the labia minora into which the urinary meatus (urethral A penis (plural penises or penes (/-n i z /)) is the primary sexual organ that male animals use to inseminate females (or hermaphrodites) during copulation. In anatomy, the orbit is the cavity or socket of the skull in which the eye and its appendages are situated. The maxillary sinuses are the largest and the most inferior of the paranasal sinuses. The inner surface of the concha is covered by a mucous membrane that contains large vascular spaces that can change in size in order to control the width of the nasal cavity. The cranial nerves emerge from the central The maxillary sinuses are innervated by the Earwax, also known as cerumen, is a yellowish, waxy substance secreted in the ear canals. The vulval vestibule is a part of the vulva between the labia minora into which the urinary meatus (urethral The outside of the foreskin is a continuation of the skin on the shaft of the penis, but the inner foreskin is a mucous membrane like the inside of the eyelid or the mouth. The definition of mechanically separated meat (MSM) should be a generic one covering all methods of mechanical separation. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue.It is mostly of endodermal origin and is continuous with the skin at body openings such as the eyes, eyelids, ears, inside the nose, inside the mouth, Development. The cranial nerves emerge from the central An anatomic ring is formed by the fused bones of the ilium, ischium and pubis attached to the sacrum. Nasal Cavity Definition. The definition of mechanically separated meat (MSM) should be a generic one covering all methods of mechanical separation. Spiral ganglion The spiral ganglion is the sensory ganglion of the cochlear branch of the vestibulocochlear nerve (CN VIII). Gross anatomy. Each maxillary sinus is drained by one or more openings (maxillary ostia) into the middle nasal meatus.Similar to the frontal sinuses, the maxillary sinuses are also drained at the semilunar hiatus.. The mucocutaneous zone occurs where the outer and inner foreskin meet. The frontal sinuses are one of the four pairs of paranasal sinuses that are situated behind the brow ridges. The outer layer of connective tissue that surrounds an artery, or vein the tunica externa, is also called the tunica adventitia.. To some degree, its role is complementary to that of the serosa, which also provides a layer of tissue surrounding an organ. The intrinsic muscles of the external ear are: . Mastoid Process Location. In males, the urethra allows for the expulsion of both urine and semen. The parapharyngeal space is shaped like an inverted pyramid, with its base at the skull base, with its apex inferiorly pointing towards the greater cornu of the hyoid bone 2.. The main structures of the vulva are: the mons pubis, the labia majora and labia minora, the external parts of the clitoris the clitoral hood and the glans, the urinary meatus, the vaginal opening and hymen, and Bartholin's and Skene's vestibular glands. Like the eyelid, the foreskin is free to move after it separates from the glans, which usually occurs before or during puberty. The nose is one of the primary sensory organs responsible for the sense of smell, while it also plays major roles in respiration and speech production [1].The nasal cavity lies just behind the two nostrils and forms the interiors of the nose.. Definition. A bone is a rigid organ that constitutes part of the skeleton in most vertebrate animals. A penis (plural penises or penes (/-n i z /)) is the primary sexual organ that male animals use to inseminate females (or hermaphrodites) during copulation. ; The helicis minor is an oblique fasciculus, covering the crus helicis. Cetacea (/ s t e /; from Latin cetus 'whale', from Ancient Greek () 'huge fish, sea monster') is an infraorder of aquatic mammals that includes whales, dolphins, and porpoises.Key characteristics are their fully aquatic lifestyle, streamlined body shape, often large size and exclusively carnivorous diet. The outer layer of connective tissue that surrounds an artery, or vein the tunica externa, is also called the tunica adventitia.. To some degree, its role is complementary to that of the serosa, which also provides a layer of tissue surrounding an organ. The glomerulus is a small tuft of capillaries containing two cell types. The outside of the foreskin is a continuation of the skin on the shaft of the penis, but the inner foreskin is a mucous membrane like the inside of the eyelid or the mouth. The mucocutaneous zone occurs where the outer and inner foreskin meet. The adventitia (advnt) is the outer layer of fibrous connective tissue surrounding an organ..

The mastoid process In general, vestibule is a small space or cavity at the beginning of a canal. Bones protect the various other organs of the body, produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility.Bones come in a variety of shapes and sizes and have a complex internal and external structure. The urethra is a hollow tube positioned between the urinary bladder and urinary meatus which takes urine stored in the bladder out of the body. The renal corpuscle is composed of two structures, the glomerulus and the Bowman's capsule.

A penis (plural penises or penes (/-n i z /)) is the primary sexual organ that male animals use to inseminate females (or hermaphrodites) during copulation. Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), of which there are conventionally considered twelve pairs.Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck, including the special senses of vision, taste, smell, and hearing.. The mastoid process is a smooth conical projection of bone located at the base of the mastoid area of the temporal bone. external auditory canal, also called external auditory meatus, or external acoustic meatus, passageway that leads from the outside of the head to the tympanic membrane, or eardrum membrane, of each ear.

Spiral ganglion The spiral ganglion is the sensory ganglion of the cochlear branch of the vestibulocochlear nerve (CN VIII). Definition. The human nose is the most protruding part of the face.It bears the nostrils and is the first organ of the respiratory system.It is also the principal organ in the olfactory system.The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum which separates the nostrils and divides the nasal cavity into two. In human females and other primates, the urethra connects to the urinary meatus above the vagina, whereas in marsupials, the female's urethra empties into the urogenital sinus. In addition it contains the cell bodies for fibers that gather sensory information from the nasal cavity, part of the soft palate, and the sinus cavities, the auricle and the external auditory meatus . The inner surface of the concha is covered by a mucous membrane that contains large vascular spaces that can change in size in order to control the width of the nasal cavity. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue.It is mostly of endodermal origin and is continuous with the skin at body openings such as the eyes, eyelids, ears, inside the nose, inside the mouth, The structure of the external auditory canal is the same in all mammals. It is anatomically homologous to the clitoral glans.The glans penis is part of the male reproductive system in humans and other mammals where it may appear smooth, spiny, The outside of the foreskin is a continuation of the skin on the shaft of the penis, but the inner foreskin is a mucous membrane like the inside of the eyelid or the mouth. The human nose is the most protruding part of the face.It bears the nostrils and is the first organ of the respiratory system.It is also the principal organ in the olfactory system.The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum which separates the nostrils and divides the nasal cavity into two. The mastoid process fat (main component) vessels internal maxillary artery, depending on its course ascending pharyngeal artery, depending on its course; pterygoid venous plexus, in its portion It is composed of central and peripheral portions. Internal and external urethral sphincter muscles control micturition. The helicis major is a narrow vertical band situated upon the anterior margin of the helix.It arises below, from the spina helicis, and is inserted into the anterior border of the helix, just where it is about to curve backward. Other features include the pudendal cleft, pubic hair, sebaceous glands, the vulval vestibule, and the urogenital triangle. The temporal bone is ossified from eight centers, exclusive of those for the internal ear and the tympanic ossicles: one for the squama including the zygomatic process, one for the tympanic part, four for the petrous and mastoid parts, and two for the styloid process.Just before the end of prenatal development [Fig. The renal corpuscle is composed of two structures, the glomerulus and the Bowman's capsule.
