Anatomy of the Scalp

The video tutorial by Dr. Morton covers the anatomy of the scalp, detailing its five layers: skin, connective tissue, aponeurosis, loose connective tissue, and pericranium. It explains the cutaneous innervation by various nerves and the vascular supply from branches of the external and internal carotid arteries. The tutorial highlights the functional significance of these structures, including the role of the scalp in heat conservation and the implications of scalp injuries.
