Carotid Arteries - Internal Carotid Artery (ICA), External Carotid Artery (ECA) - Anatomy of Neck

Explore the comprehensive anatomy of the carotid arterial system in this 19-minute educational video that covers the essential vascular structures of the head and neck region. Learn about the common carotid artery and its bifurcation into the internal carotid artery (ICA) and external carotid artery (ECA), including their anatomical relationships and clinical significance. Discover the detailed anatomy of specialized structures such as the carotid sinus and carotid body, along with their innervation by the vagus nerve (CN X) and glossopharyngeal nerve (CN IX). Examine the internal carotid artery's course through the cavernous sinus and its major branches including the ophthalmic artery, while understanding its connections to the cerebral circulation through the anterior and posterior communicating arteries. Study the relationship between the ICA and major cerebral vessels including the anterior cerebral artery (ACA), middle cerebral artery (MCA), and posterior cerebral artery (PCA). Investigate the external carotid artery's branches, particularly the maxillary artery, and understand the broader context of neck anatomy and dural venous sinuses in relation to these critical vascular structures.
