Occipital artery

The occipital artery arises from the external carotid artery opposite the facial artery, its path is below the posterior belly of digastric to the occipital region. This artery supplies blood to the back of the scalp and sterno-mastoid muscles. Other muscles it supplies are deep muscles in the back and neck.

Small anastomotic channels exist between the occipital artery (OA) and muscular branches of the vertebral artery; however, no direct connection has been reported between an extradural origin of the posterior inferior cerebellar artery (PICA) and the OA.
