n.
A small cavity or chamber within a body or organ, especially:
a. The chamber on the left side of the heart that receives arterial blood from the left atrium and contracts to force it into the aorta.
b. The chamber on the right side of the heart that receives venous blood from the right atrium and forces it into the pulmonary artery.
c. Any of the interconnecting cavities of the brain.

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

ventricle

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

  1. a chamber of the heart, having thick muscular walls, that receives blood from the ATRIUM, and pumps it to the arteries.
  2. 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).

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.

ven·tri·cle

(ven'tri-kĕl) [TA]
A normal cavity, as of the brain or heart.
[L. ventriculus, dim. of venter, belly]

After birth, the usual cardiac output and peripheral resistance increase and decrease of the resistance of the lungs might have led to the augmented blood flow through the fistula into the right ventricle. This might have contributed to a reduced systemic and subendocardial perfusion, leading to subendocardial ischemia and finally low systemic perfusion.
Current treatment--called "single-ventricle palliation"--uses the right ventricle to support the entire circulation through a series of surgeries.
However, exploring the right ventricle with imaging diagnostic tools is still a challenge.
Considering that we aim to classify all images as left ventricle object or nonleft ventricle object, the BPNN has two output neurons.
