RT Journal Article T1 Anatomical relationships of the cleidoatlanticus muscle: Interpretation about its origin A1 Rodríguez Vázquez, José Francisco A1 Mérida Velasco, José Ramón A1 Sanz Casado, José Vicente A1 Verdugo López, Samuel A1 Cuadra Blanco, Crótida De La AB An unusual muscular variation, the cleidoatlanticus muscle, was observed on the right-hand side of the lateral cervical region. The upper third of the muscle was concealed by the sternocleidomastoid muscle. There was a loop of nerves surrounding the muscle, formed by an anastomosis between the transverse cervical nerve and the greater auricular nerve. A fine vascular-nervous pedicle (formed by a small branch from the transverse cervical artery and by a branch from the medial supraclavicular nerve) entered the deep surface of the muscle at the junction of its middle and lower thirds. Taking into account the relationships that presented with the superficial branches of the cervical plexus, we consider that the cleidoatlanticus muscle is derived from the sternocleidomastoid muscle.
