Arteries of the Head

Description

Rendered in lateral profile, the head and upper neck are overlaid with a translucent vascular map that tracks the arterial tree from the cervical inflow to the intracranial branches. The common carotid ascends in the carotid sheath and bifurcates near the superior border of the thyroid cartilage into the internal carotid artery, coursing deep and anterior to the cervical vertebrae, and the external carotid artery, giving off more superficial branches toward the face and scalp. Anteriorly, facial and labial branches arc across the mandible and midface, while the superficial temporal artery climbs superiorly in front of the auricle and the occipital artery runs posteriorly toward the scalp. Deeper within the cranial cavity, the internal carotid contributes to the anterior circulation, feeding the anterior and middle cerebral artery territories and their finer arteriolar networks. Clean landmarks. Clear flow. That distribution matters because head and neck arterial anatomy governs where ischemia, hemorrhage, and iatrogenic injury declare themselves. A lateral, see-through treatment makes it easier to teach the difference between external carotid supply to the scalp and face versus internal carotid supply to the brain, a distinction that comes up in stroke localization, carotid endarterectomy planning, and interpretation of collateral flow across the circle of Willis during internal carotid stenosis. It also supports common procedural risk discussions, from temporal artery biopsy for suspected giant cell arteritis to the danger zone around the facial artery during submandibular approaches. Use this artwork in neuroanatomy and head and neck anatomy courses, stroke and vascular surgery teaching files, or medical publishing layouts explaining carotid bifurcation disease, extracranial to intracranial anastomoses, and scalp vascular supply in reconstructive planning.
