The roof is composed of the cerebellum.
Fourth ventricle roof and floor.
The caudal tip of the fourth ventricle where it becomes the central canal is known as the obex.
The obex is also a.
The fourth ventricle has an anterior ventral floor with a characteristic diamond shape named the rhomboid fossa and a posterior dorsal tent shaped roof.
The bounds of the 4th ventricle contain sidelong boundaries a roof and a floor lateral bounds lateral walls.
Csf produced and or flowing into the fourth ventricle can exit to the subarachnoid space through lateral apertures and a single median aperture located in the inferiorportion of the roof.
The fourth ventricle contains cerebrospinal fluid.
Roof of the fourth ventricle formed by thin laminae of white matter.
This region contains the cardiorespiratory deglutition and vasomotor centers.
Inside the brain there are four cavities called ventricles.
This ventricle has a roof and a floor.
The fourth ventricle has a roof at its upper posterior surface and a floor at its lower anterior surface and side walls formed by the cerebellar peduncles nerve bundles joining the structure on the posterior side of the ventricle to the structures on the anterior side.
The fourth ventricle has lateral boundaries a roof and a floor.
The lowermost portion of the floor of the fourth ventricle is called the calamus scriptorius as it appears to resemble the tip of a pen.
