Occipital Artery, Posterior View

Description

Arising from the posterior aspect of the external carotid artery, the occipital artery sweeps posteriorly deep to the posterior belly of the digastric and the sternocleidomastoid region, then emerges in the occipital scalp to ascend toward the vertex. Along the back of the head it courses close to the superior nuchal line on the occipital bone, sending tortuous branches superiorly and medially across the occiput. Posterior cranial landmarks and sutures frame the vessel, while the cervical vertebrae sit inferiorly in the midline as the artery’s descending segment approaches the upper neck. Small-caliber rami and arterioles are shown distributing within the posterior scalp. This posterior projection matters when you need to reconcile surface landmarks with deep vascular anatomy. The occipital artery is a frequent source vessel in scalp and posterior cranial reconstruction, and it becomes a real operative consideration during suboccipital approaches, posterior cervical exposures, and harvest of occipital artery based flaps. It also anchors teaching around occipital neuralgia, where the greater occipital nerve crosses the nuchal musculature near the artery and can be targeted for nerve blocks, with arterial proximity informing safe needle placement. A surgical landmark. Use this artwork for gross anatomy teaching of head and neck vasculature, for operative atlases that discuss posterior scalp incisions and suboccipital dissections, and for clinical education materials on occipital artery palpation, scalp laceration bleeding control, and occipital nerve block technique.
