ventricle of Arantius  the rhomboid fossa, especially its lower end.

double-inlet ventricle  a congenital anomaly in which both atrioventricular valves, or a single common atrioventricular valve, open into a single ventricle, which usually resembles the left ventricle morphologically (double-inlet left v.) but may resemble the right (double-inlet right v.) or neither or both ventricles.

double-outlet left ventricle  a rare anomaly in which both great arteries arise from the left ventricle, often associated with a hypoplastic right ventricle, ventricular septal defect, and other cardiac malformations.

double-outlet right ventricle  incomplete transposition of the great ventricles in which both the aorta and the pulmonary artery arise from the right ventricle, associated with a ventricular septal defect.

fifth ventricle  the median cleft between the two laminae of the septum pellucidum.

fourth ventricle of cerebrum  a median cavity in the hindbrain, containing cerebrospinal fluid.

ventricle of larynx  the space between the true and false vocal cords.

lateral ventricle of cerebrum  the cavity in each cerebral hemisphere, derived from the cavity of the embryonic tube, containing cerebrospinal fluid.

left ventricle of heart  the lower chamber of the left side of the heart, which pumps oxygenated blood out through the aorta to all the tissues of the body.

Morgagni's ventricle  v. of larynx.

pineal ventricle  an extension of the third ventricle into the stalk of the pineal body.

right ventricle of heart  the lower chamber of the right side of the heart, which pumps venous blood through the pulmonary trunk and arteries to the capillaries of the lungs.

third ventricle of cerebrum  a narrow cleft below the corpus callosum, within the diencephalon between the two thalami.

Verga's ventricle  an occasional space between the corpus callosum and fornix.

ven·tri·cle (vntr-kl)

n.

A small cavity or chamber within a body or organ, especially the right or left ventricle of the heart or any of the interconnecting ventricles of the brain.

---

Ventricle

A 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.

cardiac ventricle

the single fetal cardiac ventricle, formed by the looping of the bulboventricle; divided later by the growth of the interventricular septum as a projection from the wall of the bulboventricle.

fifth ventricle

the median cleft between the two laminae of the brain's septum lucidum.

fourth ventricle

a median, horizontally disposed, rhomboid cavity in the hindbrain, between the cerebellum and medulla, containing cerebrospinal fluid.

gastric ventricle

stomach.

laryngeal ventricle

a variably developed cavity of the larynx that opens into the laryngeal vestibule by a cleft between the vestibular and vocal folds; well developed in dogs and horses and especially certain apes.

lateral ventricle

the cavity in each cerebral hemisphere, derived from the cavity of the embryonic tube, containing cerebrospinal fluid and communicating with the third ventricle.

left ventricle

the lower chamber of the left side of the heart, which pumps oxygenated blood out through the aorta to all the tissues of the body.

pineal ventricle

an extension of the third ventricle into the stalk of the pineal body.

right ventricle

the lower chamber of the right side of the heart, which pumps venous blood through the pulmonary trunk and arteries to the capillaries of the lung.

third ventricle

a vertically disposed, ring-shaped space that contains cerebrospinal fluid and that communicates anteriorly with the lateral ventricles and caudally with the cerebral aqueduct within the diencephalon between the two thalami.
