A) The Neurocranium (Chondrocranium). The neurocranium is the portion of the skull that protects the brain and certain sense organs. In the Elasmobranchs (sharks and rays) it is composed of cartilage (chondrocranium), but in most other vertebrates, the cartilage is replaced by bone (endochondral or replacement bone).he dermatocranium forms most of the skull and functions as a protective shield for the brain. See the dermal armour of Amia, the bowfin, which sits on the cartilaginous neurocranium. In other animal groups the cartilage disappears and when you look down on the skull you are looking at the bones of the dermatocranium.
