FAZLIOGULLARI, Zeliha et al. The Levator Claviculae Muscle and Unilateral Third Head of the Sternocleidomastoid Muscle: Case Report. Int. J. Morphol. [online]. 2010, vol.28, n.3, pp.929-932. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022010000300043.

A rare case of unilateral third head of sternocleidomastoid and an extra muscle levator claviculae were determined unilaterally in a 70-year-old male cadaver during the routine dissections. In the left neck side, it was observed that the sternocleidomastoid muscle also had a third part in addition to known sternal and clavicular heads and levator claviculae muscle which arose from the posterior tubercle of the transverse process of the 3rd cervical vertebra and attached to the posterior margin of the clavicle. An awareness of this variations may be important because of its close relationship with neurovascular structures during neck operations.

Keywords : Levator claviculae muscle; Sternocleidomastoid muscle; Neck; Anatomic variation.
