terminal ventricle

ter·mi·nal ven·tri·cle

[TA] a dilation of the central canal of the spinal cord at the tip of the medullary cone. Synonym(s): ventriculus terminalis [TA]

ventricle

(ven'tri-kl) [L. ventriculus, a little belly] 1. A small cavity.

VENTRICLES OF THE BRAIN: Left lateral view2. One of the four, interconnected, ependyma-lined cavities inside the brain in which cerebrospinal fluid is generated continuously. See: illustration

ventricle of Arantius

See: Arantius, Julius Caesar

fifth ventricle

An unofficial name for the space between the two laminae of the septum pellucidum inside the brain.

fourth ventricle

The most caudal of the cerebrospinal fluid (CSF)-filled cavities inside the brain. The fourth ventricle extends beneath the cerebellum in the roof of the hindbrain from the caudal end of the cerebral aqueduct to the central canal of the medulla (above the middle of the olivary nuclei). The choroid plexus inside the fourth ventricle adds CSF to the fluid draining through the cerebral aqueduct from the third ventricle. CSF flows out of the fourth ventricle into the subarachnoid space surrounding the brain and spinal cord, exiting through three small openings: the median aperture (foramen of Magendie) and the two lateral apertures (foramina of Luschka).

laryngeal ventricle

Inside the larynx, the disk-shaped space below the vestibular folds and above the vocal folds.

lateral ventricle

One of the two mirror-image, cerebrospinal fluid (CSF)-filled cavities inside the cerebral hemispheres of the brain. Each lateral ventricle is C-shaped and runs parallel to the caudate nucleus and the fornix, from deep inside the frontal lobe to far into the temporal lobe; a tapering branch, the posterior horn, of each lateral ventricle extends deep into the occipital lobe. CSF from the intraventricular choroid plexus continually exits each lateral ventricle into the single third ventricle through an interventricular foramen (foramen of Monroe).

left ventricle

The muscular chamber of the heart that receives blood from the left atrium and that pumps it into the systemic circulation via the aorta.

ventricle of Morgagni

Laryngeal ventricle.

pineal ventricle

The pineal recess of the third ventricle of the brain.

right ventricle

The muscular chamber of the heart that receives blood from the right atrium and that pumps it into the lungs via the pulmonary trunk.

terminal ventricle

Ventriculus terminalis

third ventricle

The thin, disk-shaped cavity in the midline of the brain between the left and right thalami that is filled with cerebrospinal fluid (CSF). The lamina terminalis forms the front wall of the third ventricle, the fornices overlie the third ventricle, and the pineal body hangs outside the back top (dorsocaudal) corner. An extension of the third ventricle continues below the thalami and separates the walls of the left and right hypothalami. CSF flows through the two interventricular foramina into the rostral end of the third ventricle from the lateral ventricles. Along with CSF added by the choroid plexus of the third ventricle, CSF flows out of the third ventricle through the narrow cerebral aqueduct and into the fourth ventricle. Synonym: ventriculus
