This document provides an anatomy review of the bones of the skull, skull bones and base viewed internally, and the major arteries of the head and neck region. Lists of numbered skull bones and key structures are given for the external and internal views of the skull. A diagram labels the main branches arising from the external and internal carotid arteries in the head and neck. Brief discussions are included on the temporomandibular joint and infratemporal fossa.
