    Study Notes

    • The scalp consists of five layers: Skin, Dense Connective Tissue, Epicranial Aponeurosis, Loose Areolar Connective Tissue and Periosteum.
    • The loose connective tissue layer is considered the "danger area" of the scalp due to the emissary veins.
    • The scalp receives a rich arterial supply via the external carotid artery and the ophthalmic artery.
    • The scalp is innervated by branches of the trigeminal nerve or the cervical nerve roots.
    • Deep lacerations to the scalp tend to bleed profusely due to arterial supply and emissary veins.
    • The venous drainage of the scalp can be divided into superficial and deep components.
    • The superficial drainage follows the arterial supply.
    • The deep (temporal) region of the skull is drained by the pterygoid venous plexus.
    • The scalp veins connect to the diploic veins of the skull via valveless emissary veins.
    • The scalp receives additional supply from two branches of the ophthalmic artery - the supraorbital and supratrochlear arteries.
