In this topic page, we’ll learn about various anatomical aspects of the head and neck, such as the skull, eyes, teeth, nose, ears, and neck. In addition, we’ll also cover the most important blood vessels and nerves supplying each region.
The 7 cervical vertebrae form the bones of the neck that support the skull and organs of the head. The first cervical vertebra (atlas) supports and balances the head. The second vertebra (axis) allows the head to rotate laterally to the left and the right.
head, in human anatomy, the upper portion of the body, consisting of the skull with its coverings and contents, including the lower jaw.

The areas of the head include: the scalp, the infratemporal fossa, the pterygopalatine fossa, and the cranial fossae. Overlying the cranial bones, the scalp consists of 5 layers: skin, connective tissue (dense), aponeurosis, loose connective tissue and the periosteum.
