It is located in the neck, deep to sternocleidomastoid. Nerves formed from the cervical plexus innervate the back of the head, as well as some neck muscles. The branches of the cervical plexus emerge from the posterior triangle at the nerve point, a point which lies midway on the posterior border of the Sternocleidomastoid.
Branches
Has two types of branches: cutaneous and muscular.- Cutaneous (4 branches):
- Lesser occipital nerve - innervates lateral part of occipital region (C2,C3)
- Greater auricular nerve - innervates skin near concha auricle and external acoustic meatus (C2&C3)
- Transverse cervical nerve - innervates anterior region of neck (C2&C3)
- Supraclavicular nerves - innervate region of suprascapularis, shoulder, and upper thoracic region (C3,C4)
- Muscular
- ansa cervicalis (loop formed from C1-C3), etc. (geniohyoid (C1 only), thyrohyoid (C1 only), sternothyroid, sternohyoid, omohyoid)
