(from C2 and C3 roots) ascends superiorly across SCM. Supplies the skin over parotid, posterior auricle, and skin from mandible to mastoid process

roof of posterior cervical triangle

what attaches to the pharyngeal tubercle?
innervation of stylopharyngeus
Head bends to affected side and face turns away.Facial asymmetry can occur, because of growth retardation on affected side.

posterior border of the posterior cervical triangle
innervation of platysma
provides motor innervation to most of the muscles of the tongue
originates chiefly from the C4 nerve root (but receives contributions from C3 and C5. innervates the diaphragm.

the surgical creation of an artificial airway in the trachea (windpipe) on the anterior surface of the neck.
innervation of the sternohyoid
the largest and most clinically important fascial interspace of the neck because it is the major pathway for the spread of infection
