The nerve point of the neck (often referred to as Erb’s point) is a common pathway for cutaneous nerves of the neck arising from the cervical plexus. Typically found just superior to the midpoint of the posterior margin of SCM, four cutaneous nerve trunks (served by Ventral Primary Rami of various spinal nn.) radiate from the nerve point of the neck:
lesser occipital n. (C2, C3)
great auricular n. (C2, C3)
transverse cervical n. (C2, C3)
supraclavicular n. (C3, C4)
