Anatomy, Head and Neck, Occipital Nerves

Excerpt

The occipital nerves are a group of nerves that arise from the C2 and C3 spinal nerves. They innervate the posterior scalp up as far as the vertex and other structures as well, such as the ear. There are three major occipital nerves in the human body: the greater occipital nerve (GON), the lesser (or small) occipital nerve (LON), and the third (or least) occipital nerve (TON).
