The upper triangular part is formed by the posterior surface of the pons.
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.
Its rhomboid in shape diamond shaped and as a result of its shape the floor of the 4th ventricle is usually referred to as rhomboid fossa.
The cerebellum forms the top of the ventricle commonly referred to as the roof the rhomboid fossa forms the bottom of the ventricle which is referred to as floor and the cerebellar peduncles form the sides or walls.

The floor of fourth ventricle is diamond shaped and is also known as rhomboid fossa.
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 floor of the fourth ventricle is also referred to as the rhomboid fossa because of its shape.
It s divisible into 2 parts.
