| hypothalamus | The ventral part of the diencephalon that forms the floor and part of the lateral wall of the third ventricle. Anatomically, it includes the preoptic area, optic tract, optic chiasm, mammillary bodies, tuber cinereum, infundibulum, and neurohypophysis, but for physiological purposes the neurohypophysis is considered a distinct structure. The hypothalamus may be divided into five regions or areas (area hypothalamica rostralis, area hypothalamica dorsalis, area hypothalamica intermedia, area hypothalamica lateralis and area hypothalamica posterior) or into three longitudinal zones (periventricular zone, medial zone, and lateral zone). The hypothalamic nuclei constitute that part of the corticodiencephalic mechanism that activates, controls and integrates the peripheral autonomic mechanisms, endocrine activity, and many somatic functions, e.g., a general regulation of water balance, body temperature, sleep, and food intake, and the development of secondary sex characteristics. The hypothalamus secretes vasopressin and oxytocin, which are stored in the pituitary, as well as many releasing factors (hypophysiotropic hormones), by means of which it exerts control over functions of the adenohypophysis [Brenda]. | — |
| dura mater | The tough fibrous membrane covering the brain and the spinal cord and lining the inner surface of the skull. It is the outermost of the three meninges that surround the brain and spinal cord [Brenda]. | — |
| third ventricle | The third ventricle (ventriculus tertius) is one of four connected fluid-filled cavities comprising the ventricular system within the human brain. It is a median cleft between the two thalami, and is filled with cerebrospinal fluid (CSF) [Wikipedia: http://en.wikipedia.org/wiki/Third_ventricle]. | — |
| cerebellum cortex | The thin gray surface layer of the cerebellum, consisting of an outer molecular layer or stratum moleculare, a single layer of purkinje cells (the ganglionic layer), and an inner granular layer or stratum granulosum [Biology-Online: http://www.biology-online.org/dictionary/Cerebellar_cortex]. | cortex cerebelli; cerebellar cortex |
| rectum | The terminal part of the intestine from the sigmoid flexure to the anus [Brenda]. | — |
| cerebral cortex | The surface layer of gray matter of the cerebrum that functions chiefly in coordination of sensory and motor information [Brenda]. | — |
| subthalamus | The subthalamus is a part of the diencephalon. Its major part is the subthalamic nucleus. Functionally, it also encompasses the globus pallidus, which is topographically part of the telencephalon [Wikipedia: http://en.wikipedia.org/wiki/Subthalamus]. | — |
| mammary gland | The specialized accessory gland of the skin of female mammals that secretes milk. In the human female, it is a compound tubuloalveolar gland composed of 15 to 25 lobes arranged radially about the nipple and separated by connective and adipose tissue, each lobe having its own excretory (lactiferous) duct opening on the nipple. The lobes are subdivided into lobules, with the alveolar ducts and alveoli being the secretory portion of the gland [Brenda]. | — |
| myometrium | The smooth muscle coat of the uterus, which forms the main mass of the organ [Brenda]. | — |
| membranous labyrinth | The receptors for the senses of equilibrium and hearing are housed within a collection of fluid filled tubes and chambers known as the membranous labyrinth. The membranous labyrinth is lodged within the bony labyrinth and has the same general form; it is, however, considerably smaller and is partly separated from the bony walls by a quantity of fluid, the perilymph [Wikipedia: http://en.wikipedia.org/wiki/Membranous_labyrinth]. | — |
| medulla oblongata | The part of the vertebrate brain that is continuous posteriorly with the spinal cord and that contains the centers controlling involuntary vital functions [Brenda]. | — |
| colon | The part of the large intestine that extends from the cecum to the rectum [Brenda]. | — |
| midbrain | The middle of the three primary divisions of the developing vertebrate brain or the corresponding part of the adult brain [Brenda]. | — |
| metathalamus | The metathalamus is a composite structure of the thalamus, consisting of the medial geniculate nucleus and the lateral geniculate nucleus [Wikipedia: http://en.wikipedia.org/wiki/Metathalamus]. | — |
| cerebral aqueduct | The mesencephalic duct, also known as the aqueductus mesencephali, aqueduct of Sylvius or the cerebral aqueduct, contains cerebrospinal fluid (CSF), is within the mesencephalon (or midbrain) and connects the third ventricle in the diencephalon to the fourth ventricle within the region of the mesencephalon and metencephalon, located dorsal to the pons and ventral to the cerebellum [Wikipedia: http://en.wikipedia.org/wiki/Cerebral_aqueduct]. | — |
| thalamus | The largest subdivision of the diencephalon that consists chiefly of an ovoid mass of nuclei in each lateral wall of the third ventricle and functions in the integration of sensory information [Brenda]. | — |
| corpus callosum | The great band of commissural fibers uniting the cerebral hemispheres of higher mammals including humans [Brenda]. | — |
| glans | The glans (Latin for "acorn") is a vascular structure located at the tip of the penis in men or a homologous genital structure of the clitoris in women [Wikipedia: http://en.wikipedia.org/wiki/Glans]. | — |
| fovea centralis | The fovea centralis, also generally known as the fovea (the term fovea comes from the Latin, meaning pit or pitfall), is a part of the eye, located in the center of the macula region of the retina [Wikipedia: http://en.wikipedia.org/wiki/Fovea_centralis]. | — |
| fourth ventricle | The fourth ventricle is one of the four connected fluid-filled cavities within the human brain. The fourth ventricle extends from the cerebral aqueduct (aqueduct of Sylvius) to the obex, and is filled with cerebrospinal fluid (CSF). The fourth ventricle has a characteristic diamond shape in cross-sections of the human brain. It is located within the pons or in the upper part of the medulla [Brenda]. | — |
| pia mater | The fine vascular membrane that closely envelops the brain and spinal cord under the arachnoid and the dura mater [Brenda]. | — |
| endometrium | The endometrium is the inner membrane of the mammalian uterus [Wikipedia: http://en.wikipedia.org/wiki/Endometrium]. | — |
| external acoustic meatus | The ear canal (external auditory meatus, external acoustic meatus) (meatus acusticus externus) , is a tube running from the outer ear to the middle ear. The adult human ear canal extends from the pinna to the eardrum and is about 35 mm in length and 5 to 10 mm in diameter [Wikipedia: http://en.wikipedia.org/wiki/Ear_canal]. | — |
| cervix | The cervix (from the Latin cervix uteri, meaning "neck of the womb") is the lower, narrow portion of the uterus where it joins with the top end of the vagina. It is cylindrical or conical in shape and protrudes through the upper anterior vaginal wall. Approximately half its length is visible with appropriate medical equipment; the remainder lies above the vagina beyond view. The cervix has an opening to allow sperm and menstrual fluid to move through [Wikipedia: http://en.wikipedia.org/wiki/Cervix]. | — |
| epithalamus | The caudal part of the roof and the adjoining lateral walls of the third ventricle of the diencephalon, comprising the habenular nuclei and their commissure, pineal body, and commissure of the epithalamus [Brenda]. | — |
