Blood Vessels of the Head

Description

Sweeping across the calvaria and upper cervical region, the cranial vasculature is rendered with arteries in red and veins in blue, allowing immediate separation of inflow and outflow pathways. Superficial scalp vessels course over the outer table of the skull while deep channels track toward the cranial base, where the internal carotid and vertebral systems would be expected to contribute to intracranial circulation. Inferiorly, paired common carotid arteries ascend in the neck beside the internal jugular veins, while the vertebral arteries run superiorly through the transverse foramina of the cervical vertebrae. Bony landmarks of the cervical spine remain exposed for orientation. Such a view matters when teaching how extracranial and cervical vessels relate to rigid skeletal corridors and potential compression points. The vertebral artery’s passage through the transverse foramina and its proximity to the atlantoaxial region is a frequent reference in discussions of vertebrobasilar insufficiency and in the anatomy behind cervical manipulation related vascular injury. Carotid bifurcation anatomy also underpins endarterectomy planning and helps explain why internal jugular cannulation targets a structure that lies lateral to the carotid artery in most patients. Small shifts in spatial relationships change risk. Neuroanatomy, head and neck anatomy, and surgical anatomy courses can use this plate to pair vascular pathways with palpable and radiographic landmarks, from the carotid sheath to the upper cervical vertebrae. It also suits textbook figures on cerebral and cervical circulation, stroke pathways, and approaches to central venous access and carotid surgery.
