The cavity in the rhombencephalon located between the medulla oblongata, the pons, and the isthmus ventrally and anterior and the cerebellum dorsally and posterior. image
one of four open spaces within the brain; located in the area between the cerebellum and the pons varolii of the brainstem
Ventricle (a normal cavity) of the rhombencephalon of the brain; a cavity of irregular tent-like shape extending from the obex frontward to its communication with the sylvian aqueduct, enclosed between the cerebellum and the rhombencephalic tegmentum. The ventricle of the brain which lies between the cerebellum and the brainstem. It expresses CSF into the subarachnoid space via the two lateral foramina of Luschka and the single medial foramen of Magendie.
An elongate ventricle of the metencephalon (pons and cerebellum) and the myelencephalon (medulla oblongata) of the brain; the roof contains a region of choroid plexus.
an irregular ventricle between the third ventricle and the central canal of the spinal cord
One of the spinal fluid pathways in the midline of the brain, between the brainstem and the cerebellum.
The fourth ventricle is one of the four connected fluid-filled cavities within the human brain. These cavities, known collectively as the ventricular system, consist of the left and right lateral ventricles, the third ventricle, and the fourth ventricle. The fourth ventricle extends from the cerebral aqueduct (aqueduct of Sylvius) to the obex, and is filled with cerebrospinal fluid (CSF).
