33. Fig The approximate segmental distribution of the cutaneous nerves on the front of the trunk. The contribution from the first thoracic spinal nerve is not shown and the considerable overlap that occurs between adjacent segments is not indicated.

Deep in the neck under the sternocleidomastoid muscle
Formed by first 4 cervical nerves (C1 – C4)
Most are cutaneous nerves
