The head and neck are two examples of the perfect anatomical marriage between form and function, mixed with a dash of complexity. The neck is resilient enough to sustain a five kilogram weight 24/7, yet sufficiently mobile to move it in several directions. On the other end, the head is durable enough to protect the fragile brain but intricately designed to facilitate the passage of the complex neurovascular network.
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 skull is a strong, bony capsule that rests on the neck and encloses the brain. It consists of two major parts: the neurocranium (cranial vault) and the viscerocranium (facial skeleton). The neurocranium is the part enveloping the brain and is formed out of two parts; the skull base that supports the brain and the calvaria (skullcap) that sits on top of the base, covering the brain. The viscerocranium supports mainly the facial muscles and a variety of anatomical structures.
