| ventriculus quartus | A cavity of irregular tentlike shape extending from the obex rostralward to its communication with the sylvian aqueduct, enclosed between the cerebellum dorsally and the rhombencephalic tegmentum ventrally, having a rhomboid-shaped floor (rhomboid fossa) and a tentlike roof which in its caudal part is formed by the tela choroidea and the posterior medullary velum, in its middle part by the white matter of the cerebellum, and in its narrowing rostral part (recessus superior) by the anterior medullary velum. The fourth ventricle reaches its greatest width at the pontomedullary transition, where it expands laterally behind the cerebellar peduncles into the spoutlike lateral recess, and its greatest height at the fastigial recess, which reaches up into the cerebellar white matter. Direct communication of the brain's ventricle system and the subarachnoid space is established at the level of the fourth ventricle by a median opening in the tela choroidea, the medial aperture of Magendie's foramen, which opens into the cerebellomedullary cistern, and on both sides by the lateral aperture or foramen of Luschka, which connects the lateral recess with the interpeduncular cistern. Synonym: ventriculus quartus, ventricle of rhombencephalon. (05 Mar 2000) |

| ventriculus quintus | A slitlike, fluid-filled space of variable width between the left and right transparent septum, which occurs in less than 10% of human brains and may communicate with the third ventricle. Synonym: cavum septi pellucidi, Duncan's ventricle, fifth ventricle, pseudocele, pseudoventricle, sylvian ventricle, ventricle of Sylvius, ventriculus quintus, Vieussens' ventricle, Wenzel's ventricle.

| ventriculus sinister | <anatomy> The muscular chamber of the heart which accepts blood from the left atrium and ejects it into the aorta to the systemic circulation. (27 Sep 1997) |
| ventriculus terminalis | A dilation of the central canal of the spinal cord at the tip of the medullary cone. Synonym: ventriculus terminalis. (05 Mar 2000) |
| ventriculus tertius | 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) |

| ventro- | <anatomy, prefix> A combining form used in anatomy to indicate connection with, or relation to, the abdomen; also, connection with, relation to, or direction toward, the ventral side; as, ventrolateral; ventro-inguinal. Origin: L. Venter = belly. (29 Oct 1998) |
| ventrobasal nucleus | The large posterior part of the ventral nucleus of the thalamus receiving the somatic sensory lemnisci (medial lemniscus, spinothalamic tract, trigeminal lemniscus) and the ascending gustatory (taste) lemniscus, and projecting in turn by way of the internal capsule to the cortex of the postcentral gyrus. The nucleus is somatotopically organised and subdivided into a ventral posterolateral nucleus of thalamus representing the leg, a ventral posterior intermediate nucleus of thalamus representing the arm, a ventral posteromedial nucleus of thalamus representing the face, and an arcuate nucleus of thalamus receiving the gustatory lemniscus. Synonym: nucleus ventralis posterior thalami, ventrobasal nucleus. (05 Mar 2000) |

| ventricular fibrillation |
An erratic, disorganized firing of impulses from the ventricles. The ventricles quiver and are unable to contract or pump blood to the body. This is a medical emergency that must be treated with cardiopulmonary resuscitation (CPR) and defibrillation as soon as possible.

| ventricular tachycardia |
A rapid life-threatening rhythm originating from the lower chambers of the heart. The rapid rate prevents the heart from filling adequately with blood, and less blood is able to pump through the body.

| ventricle |
L. ventriculus, from venter, belly, chamber, cavity. Ventricles of the brain were so-named because it was at one time fashionable to name parts of the brain for other parts of the body that they resembled.
