Occipital Artery

The Occipital artery is a posterior branch of the external carotid artery. The occipital artery is widespread in its distribution to the head, giving off meningeal branches to the posterior cranial fossa, and muscular branches to the sternocleidomastoid and other posterior muscles.

When the external carotid or subclavian arteries are ligated or obstructed, collateral circulation is provided by the descending branch of the occipital artery
