Nerve: Third occipital nerve

While under the Trapezius, the medial branch of the posterior division of the third cervical nerve gives off a branch called the third occipital nerve, which pierces the Trapezius and ends in the skin of the lower part of the back of the head.

It lies medial to the greater occipital and communicates with it.
