| medullary striae of fourth ventricle | Slender fascicles of fibres extending transversally below the ependymal floor of the ventricle from the median sulcus to enter the inferior cerebellar peduncle. They arise from the arcuate nuclei on the ventral surface of the medullary pyramid. Synonym: striae medullares ventriculi quarti, acoustic striae, auditory striae, Bergmann's cords, medullary teniae, teniae acusticae. (05 Mar 2000) |
|---|---|
| cerebral ventricle neoplasms | Neoplasms located in the brain ventricles including the two lateral, third, and fourth ventricles. (12 Dec 1998) |
| right ventricle | The muscular chamber of the heart which accepts blood from the right atrium and pumps it through the pulmonary artery into the lungs. (27 Sep 1997) |
| choroid plexus of fourth ventricle | One of two vascular fringes of pia mater projecting on either side from the lower part of the roof of the fourth cerebral ventricle. Synonym: plexus choroideus ventriculi quarti. (05 Mar 2000) |
| choroid plexus of third ventricle | The double row of vascular projections from the undersurface of the tela choroidea where it roofs over the third ventricle. Synonym: plexus choroideus ventriculi tertii. (05 Mar 2000) |
| choroid tela of fourth ventricle | The sheet of pia mater covering the lower part of the ependymal roof of the fourth ventricle. Synonym: tela choroidea ventriculi quarti, tela choroidea inferior. (05 Mar 2000) |
| choroid tela of third ventricle | A double fold of pia mater, enclosing subarachnoid trabeculae, between the fornix above and the epithelial roof of the third ventricle and the thalami below; at each lateral margin is a vascular fringe projecting into the choroidal fissure of the lateral ventricle; on its undersurface are several small vascular projections filling the folds of the ependymal roof of the third ventricle. Synonym: tela choroidea ventriculi tertii, tela choroidea superior, triangular lamella, velum interpositum, velum triangulare. (05 Mar 2000) |
| roof of fourth ventricle | Roof of fourth ventricle, formed in its upper part by the superior medullary velum stretching between the two brachia conjunctiva (superior cerebellar peduncles), in its lower part by the inferior medullary velum composed of the choroid membrane and choroid plexus of the fourth ventricle. Synonym: roof of fourth ventricle. (05 Mar 2000) |
| Wenzel's ventricle | 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. (05 Mar 2000) |
| Morgagni's ventricle | The recess in each lateral wall of the larynx between the vestibular and vocal folds and into which the layrngeal sacculus opens. Synonym: ventriculus laryngis, laryngeal sinus, Morgagni's sinus, Morgagni's ventricle, sinus laryngeus. (05 Mar 2000) |
| heart ventricle | The lower right and left chambers of the heart. The right pumps venous blood into the lungs and the left pumps oxygenated blood into the systemic arterial circulation. (12 Dec 1998) |
| single ventricle | Congenital absence or near total absence of the ventricular septum. (05 Mar 2000) |
| sixth ventricle | An inconstant, horizontal, slitlike space between the posterior one-third of the corpus callosum and the underlying commissura fornicis (commissura hippocampi; psalterium) resulting from failure of these two commissural plates to fuse completely during foetal development; like the cavity of the septum pellucidum, the space is not a true ventricle in the sense that it did not develop from the central canal of the neural tube. Synonym: cavum psalterii, cavum vergae, sixth ventricle. (05 Mar 2000) |
| skeletal muscle ventricle | Autologous skeletal muscle that is wrapped around the heart and electrically stimulated in order to provide mechanical heart assistance. The latissimus dorsi muscle is commonly used to form this ventricle that functions to independently augment cardiac performance by pumping in series with the heart. (12 Dec 1998) |
| hypoplasia of right ventricle | Failure of development of the right ventricle resulting in its having little muscle and much connective tissue instead of the reverse. (05 Mar 2000) |
