Editing Scalp (section)

===Nerve supply===
Innervation is the connection of nerves to the scalp: the sensory and motor nerves innervating the scalp. The scalp is innervated by the following:
* [[Supratrochlear nerve]] and the [[supraorbital nerve]] from the [[ophthalmic division]] of the [[trigeminal nerve]]
* [[Greater occipital nerve]] (C2) posteriorly up to the vertex
* [[Lesser occipital nerve]] (C2) behind the ear
* [[Zygomaticotemporal nerve]] from the [[maxillary nerve|maxillary division]] of the [[trigeminal nerve]] supplying the hairless temple
* [[Auriculotemporal nerve]] from the [[mandibular division]] of the [[trigeminal nerve]]

The innervation of scalp can be remembered using the mnemonic 'Z-GLASS' for '''Z'''ygomaticotemporal nerve, '''G'''reater occipital nerve, '''L'''esser occipital nerve, '''A'''uriculotemporal nerve, '''S'''upratrochlear nerve, and '''S'''upraorbital nerve.

The motor innervation of the scalp, specifically, the [[occipitofrontalis]] muscle, is split into two main factions: the frontal belly or [[frontalis muscle]] is supplied by the [[temporal branch of facial nerve]], while the occipital belly or [[occipitalis]] is supplied by the [[posterior auricular nerve|posterior auricular branch of facial nerve]].
