One of the four, interconnected, ependyma-lined cavities inside the brain in which cerebrospinal fluid is generated continuously. See: illustrationventricle of Arantius See: Arantius, Julius Caesarfifth ventricleAn unofficial name for the space between the two laminae of the septum pellucidum inside the brain. fourth ventricleThe 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 ventricleInside the larynx, the disk-shaped space below the vestibular folds and above the vocal folds.lateral ventricleOne 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 ventricleThe 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 MorgagniLaryngeal ventricle.pineal ventricleThe pineal recess of the third ventricle of the brain.right ventricleThe muscular chamber of the heart that receives blood from the right atrium and that pumps it into the lungs via the pulmonary trunk.terminal ventricleVentriculus terminalisthird ventricleThe 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: ventriculusventricle A cavity or chamber filled with fluid, especially the two lower pumping chambers of the heart and the four fluid-filled spaces in the brain.ventricle - a chamber of the heart, having thick muscular walls, that receives blood from the ATRIUM, and pumps it to the arteries.
- four large spaces in the brain filled with CEREBROSPINAL FLUID. They occur in the CEREBRAL HEMISPHERES (lateral ventricles), FOREBRAIN (third ventricle) and MEDULLA OBLONGATA (fourth ventricle).
VentricleA cavity, as in the brain or heart. The right ventricle of the heart drives blood from the heart into the pulmonary artery, which supplies blood to the lungs.Mentioned in: Cardiac Blood Pool Scan, Congestive Cardiomyopathy, Cor Pulmonale, Hypertension, Mitral Valve Insufficiency, Mitral Valve Stenosis, Ventricular Assist Deviceven·tri·cle (ven'tri-kĕl) [TA] A normal cavity, as of the brain or heart.
