9.3 Lesson 3: Sensory Nerve of the Scalp

Sensory Nerve of the Scalp I

The main trunks of the sensory nerves lie in the superficial fascia.
The supratrochlear nerve, a branch of the ophthalmic division of the trigeminal nerve, winds around the superior orbital margin and supplies the scalp. It passes backward close to the median plane and reaches nearly as far as the vertex of the skull.
The supraorbital nerve, a branch of the ophthalmic division of the trigeminal nerve, winds around the superior orbital margin and ascends over the forehead. It supplies the scalp as far backward as the vertex.

Sensory Nerve of the Scalp II

The auriculotemporal nerve, a branch of the mandibular division of the trigeminal nerve, ascends over the side of the head from in front of the auricle. Its terminal branches supply the skin over the temporal region.
The zygomatico-temporal nerve, a branch of the maxillary division of the trigeminal nerve, supplies the scalp over the temple.

Sensory Nerve of the Scalp III

The greater occipital nerve, a branch of the posterior ramus of the second cervical nerve, ascends over the back of the scalp and supplies the skin as far forward as the vertex of the skull.
The lesser occipital nerve, a branch of the cervical plexus (C2), supplies the scalp over the lateral part of the occipital region and the skin over the medial surface of the auricle.
