The SCM: Anatomy, MSR Procedures, and Rehabilitation
The sternocleidomastoid (SCM) is a paired, superficial muscle of the anterolateral neck. Its sternal and clavicular heads arise from the manubrium and medial clavicle and ascend to the mastoid process and lateral superior nuchal line. This oblique course makes the SCM a palpable landmark for distinguishing the anterior and posterior cervical triangles.
