"Numerous arteries supply the scalp, contributing to its rich vascular supply.The arteries arise from both the internal and external carotid circulations:"
"The scalp (TA: calva) is the skin and subcutaneous tissue covering the neurocranium. It is composed of five layers and has a rich vascular supply which explains why it bleeds profusely and heals well."
"Like the face, the scalp does not have lymph nodes. Lymph drains via small lymphatic channels to the submandibular, parotid, mastoid and occipital nodes. These form a collar of nodes at the junction of the head and neck."
