| ventral sacrococcygeus muscle | <anatomy> An inconstant muscle on the pelvic surfaces of the sacrum and coccyx, the remains of a portion of the tail musculature of lower animals. Synonym: musculus sacrococcygeus ventralis, musculus sacrococcygeus anterior, ventral sacrococcygeal muscle. (05 Mar 2000) |
|---|---|
| ventral sacroiliac ligaments | The strong fibrous bands that reinforce the sacroiliac joint anteriorly. Synonym: ligamenta sacroiliaca anteriora, ventral sacroiliac ligaments. (05 Mar 2000) |
| ventral spinocerebellar tract | A bundle of fibres originating in the base of the posterior horn and zona intermedia throughout lumbosacral segments of the spinal cord, crossing to the opposite side and ascending in a peripheral position in the ventral half of the lateral funiculus. In its ascent through the rhombencephalon, the tract curves sharply dorsalward along the rostral border of the trigeminal motor nucleus, entering the cerebellum in a caudal direction over the dorsal surface of the superior cerebellar peduncle, and terminating as mossy fibres in the granular layer of the cortex of the cerebellar vermis. The bundle conveys proprioceptive and exteroceptive information largely from the opposite lower extremity. Synonym: tractus spinocerebellaris anterior, Gowers' column, Gowers' tract, ventral spinocerebellar tract. (05 Mar 2000) |
| ventral spinothalamic tract | The more anterior or ventral part of the spinothalamic tract that is involved in tactile sensation. See: spinothalamic tract. Synonym: tractus spinothalamicus anterior, ventral spinothalamic tract. (05 Mar 2000) |
| ventral splanchnic arteries | Artery's that arise on the embryo from the dorsal aorta and are distributed to the digestive tube. (05 Mar 2000) |
| ventral surface of digit | The flat of the fingers; the flexor or anterior surface of the fingers. Synonym: facies digitalis ventralis, facies digitalis palmaris, ventral surface of digit. (05 Mar 2000) |
| ventral tegmental area | A region in the mesencephalon which is dorsomedial to the substantia nigra and ventral to the red nucleus. The mesocortical and mesolimbic dopaminergic systems originate here, including an important projection to the nucleus accumbens. Overactivity of the cells in this area has been suspected to contribute to the positive symptoms of schizophrenia. (12 Dec 1998) |
| ventral tegmental decussation | See: tegmental decussations. (05 Mar 2000) |
| ventral thalamic peduncle | The massive system of fibre bundles emerging through the ventral, lateral, and anterior borders of the thalamus to join the internal capsule and parts of the corona radiata; it contains the fibres reciprocally connecting the ventral thalamic nuclei with the precentral and postcentral gyri of the cerebral cortex. Synonym: pedunculus thalami ventralis. (05 Mar 2000) |
| ventral tier thalamic nuclei | Collective term for nuclei in the ventral part of the lateral nuclear group, e.g., ventral anterior, lateral, posterolateral, and posteromedial nuclei and the medial and lateral geniculate bodies. The basoventral nuclear complex constitutes the caudal part of the ventral tier thalamic nuclei. (05 Mar 2000) |
| ventral white column | A narrow band of white substance bordering on the anterior median fissure of the spinal cord in front of the anterior gray commissure, and consisting of nerve fibres crossing over from one half of the spinal cord to the other. Synonym: commissura alba, anterior white commissure, commissura ventralis alba, ventral white column. (05 Mar 2000) |
| ventralis | Synonym: ventral. Origin: L. (05 Mar 2000) |
| ventricle | <anatomy> The paired (right and left) more muscular chambers of the heart that pump blood into the pulmonary (right ventricle) and systemic (left ventricle) circulation. (27 Sep 1997) |
| ventricle of cerebral hemisphere | A cavity shaped somewhat like a horseshoe in conformity with the general shape of the hemisphere; each lateral ventricle communicates with the third ventricle through the interventricular foramen of Monro, and expands from there forward into the frontal lobe as the anterior horn as well as caudally over the thalamus as the central part or cella media which, behind the thalamus, curves ventrally and laterally, then forward into the temporal lobe as the inferior horn; from the apex of the curve a variably sized posterior horn extends back into the white matter of the occipital lobe. The large choroid plexus of the lateral ventricle invades the cella media and the inferior horn (but not the anterior and posterior horn) from the medial side. Synonym: ventriculus lateralis, ventricle of cerebral hemisphere. (05 Mar 2000) |
| ventricle of diencephalon | A narrow, vertically oriented, irregularly quadrilateral cavity in the midplane, extending from the lamina terminalis to the rostral opening of the mesencephalic aqueduct. This ventricle communicates at its rostrodorsal corner with each of the two lateral ventricles through the left and right interventricular foramen of Monro. Its narrow roof is formed by the tela choroidea which is attached on either side to the tenia thalami; its lateral wall by the medial surface of the thalamus and, below the hypothalamic sulcus, by the hypothalamus which also forms its floor. In lateral profile, the third ventricle exhibits a number of recesses: in its floor, from before backward, 1) the preoptic recess in the acute angle between the base of the lamina terminalis and the dorsum of the optic chiasm, 2) the infundibular recess extending ventrally into the infundibulum but (in humans) not into the hypophysial stalk, and 3) the mamillary or inframamillary recess caused by the protrusion of the mamillary bodies into the ventricle. From its dorsocaudal corner, the pineal recess extends caudally into the pineal stalk. Synonym: ventriculus tertius, diacele, ventricle of diencephalon. (05 Mar 2000) |

| ventricle |
The ventricular system is a fluid conducting system within the brain. It is filled with cerebrospinal fluid (CSF) that is largely composed of water. The ventricular system serves to bathe and cushion the brain and spinal cord within their bony confines. The ventricular system consists of two large lateral ventricles in either cerebral hemisphere that extend into the temporal lobes (temporal horns) and occipital lobes (occipital horns). ...
