what is the top of the skull called
Skull The skull consists of two parts, of different embryological originâ€”the neurocranium and the facial skeleton (also called the membraneous viscerocranium). The neurocranium (or braincase) forms the protective cranial cavity that surrounds and houses the brain and brainstem. The upper areas of the cranial bones form the calvaria (skullcap). The neurocranium includes the mandible.
Internal carotid artery The internal carotid runs vertically upward in the carotid sheath, and enters the skull through the carotid canal. During this part of its course, it lies in front of the transverse processes of the upper three cervical vertebrae.
