A Study of Morphologic and Morphometric Features of Vermian Fossa and Internal Occipital Crest in Adult Indian Human Skulls in Tertiary Care Centres

Abstract

Introduction- A noticeable internal occipital crest is visible on the inside surface of the squamous portion of the occipital bone. It descends and bifurcates around the foramen magnum, enclosing a tiny depression known as the vermian fossa. The single or double occipital sinus is located in the falx cerebelli, which is connected to the crest. The fossa houses the inferior vermis of the cerebellum. A bony ridge that divides the vermian fossa into upper and lower parts might give the structure a somewhat triangular shape. There are not many research that describe the morphometric and morphologic characteristics of vermian fossa. Hence, the present study was done to evaluat the morphological and morphometric parameters of vermian fossa and internal occipital crest in the Indian adult human dry skull.
