Head and neck anatomy This article describes the anatomy of the head and neck of the human body, including the brain, bones, muscles, blood vessels, nerves, glands, nose, mouth, teeth, tongue, and throat. The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas). The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine. The skull can be further subdivided into:
Axis (anatomy) to these there is a secondary center for a thin epiphysial plate on the under surface of the body of the bone. Fractures of the dens, not to be confused with Hangman's fractures, are classified into three categories according to the Anderson–D'Alonso system: Axis (anatomy) In anatomy, the second cervical vertebra (C2) of the spine is named the axis (from Latin "axis", "axle") or epistropheus. By the atlanto-axial joint, it forms the pivot upon which the first cervical vertebra (the atlas), which carries the head, rotates. The most distinctive characteristic of this bone is the strong odontoid process known as
