Arteries of the head and neck

This video tutorial covers the anatomy and arterial blood supply of the head and neck. It begins with an overview of the main arterial sources, the common carotid and subclavian arteries, and their branches. The tutorial details the branches of the external carotid artery using a mnemonic for easy recall. It then explores the internal carotid artery, its role in brain circulation, and the subclavian system, including the vertebral artery. The video concludes with a discussion on cerebrovascular disease, focusing on strokes and their types.
