Course and relations It curves around the posterior border of the
sternocleidomastoideus muscle'
about its middle, and, passing obliquely forward beneath the external jugular vein to the anterior border of the muscle, it perforates the deep cervical fascia before dividing into an ascending branch and a descending branch beneath the platysma. The ascending branch communicates with the cervical branch of the facial nerve.'
Dissection During dissection, the sternocleidomastoid muscle is the landmark, with the transverse cervical nerve passing horizontally over this muscle from
Erb's point.
Distribution The nerve provides sensory innervation to the skin of the anterior neck between the chin and the sternum.'''''' ==Additional images==
