CHERIAN, Saju Binu y NAYAK, Satheesha. A Rare Case of Unilateral Third Head of Sternocleidomastoid Muscle. Int. J. Morphol. [online]. 2008, vol.26, n.1, pp. 99-101. ISSN 0717-9502. http://dx.doi.org/10.4067/S0717-95022008000100017.
A rare case of unilateral third head of sternocleidomastoid muscle was noted during routine dissections for undergraduate medical students. The additional third head originated from the middle third of the clavicle and joined the normal two heads (sternal and clavicular) of the muscle in the middle of the neck. The insertion and nerve supply of the muscle was normal. This case may be important for head and neck surgeons and for plastic surgeons doing muscle graft surgeries.
