The roof of fourth ventricle is the dorsal surface of the fourth ventricle . It corresponds to the ventral surface of the cerebellum . The upper portion of the roof is formed by the cerebellum.. Floor of the fourth ventricle. The cerebellar peduncles have been sectioned and the cerebellum removed in order to expose the floor of the fourth ventricle. The floor of the IV ventricle is formed by the dorsal surfaces of the pons and the rostral medulla. As seen from above, the IV ventricle is diamond-shaped.

Within the floor is the facial colliculus, sulcus limitans, and the obex. Much like other portions of the ventricular system inside the brain, the fourth ventricle develops from the area. The medulla, the pons and the midbrain are located just behind the basilar part of the occipital bone, and the dorsum sellae. The dorsal aspect of the medulla faces almost directly. The floor (i.e. the anterior edge) of the fourth ventricle constitutes the rhomboid fossa, and comprises a number of general features. A sulcus - the median sulcus - extends the length of the ventricle (from the cerebral aqueduct of the midbrain to the central canal of the spinal cord), dividing the floor into right and left halves.

The floor of the fourth ventricle is also referred to as the rhomboid fossa because of its shape. It is divisible into a right and left half by the posterior median sulcus, and into a superior and inferior triangle by the striae medullares. The upper triangular part is formed by the posterior surface of the pons. As discussed earlier, many important structures surround the fourth ventricle, namely the pons and medulla of the brainstem, as well as the cerebellum.

Roof and Floor. The fourth ventricle has a "roof" dorsally and a "floor" ventrally. The roof of the fourth ventricle is formed by the cerebellum (superior and inferior medullary vela), the floor.

The floor of the IV ventricle is divided into symmetrical halves by the midline median sulcus. Located immediately lateral to the median sulcus in the caudal pons are paired prominent bulges, the facial colliculi. These subtle surface elevations are formed by the underlying abducens nucleus and the arching fibers (interal genu) of the facial nerve.
