Study Notes
Scalp Anatomy, Arteries, Veins, and Clinical Implications
- The scalp has potential spaces that can develop into real spaces in pathological conditions such as infection or injury.
- The scalp proper can move freely over bone and is affected by the contraction of the occipitalis muscle.
- The scalp is innervated anteriorly by the supratrochlear and supraorbital nerves from the ophthalmic division of the trigeminal nerve (V1).
- Posteriorly, the scalp is innervated by the lesser and greater occipital nerves.
- Arteries of the scalp include the supratrochlear and supraorbital arteries, superficial temporal artery, and posterior auricular and occipital arteries.
- Veins of the scalp include the supratrochlear and supraorbital veins, superficial temporal vein, posterior auricular vein, and occipital vein.
- The scalp has anastomoses with diploic veins and dural venous sinuses through emissary veins.
