the rhomboideus muscle of the domestic mammals is part of the muscular set that joins the scapular waist to the axial skeleton. in these animals, the forenamed muscle has a cervical portion (m. rhomboideus cervicicis), and a thoracic portion (m. rhomboideus thoracis). unlike in the man, these parts cannot be separated. in addition, carnivores, pigs and rabbits also have a cephalic portion (m. rhomboideus capitis). in the llamas, the cephalic portion is absent, and the cervical part is poorly developed. the authors propose to add a suprascapular portion (m. rhomboideus suparsacapularis), first described by lesbre, 1903 in camels, to the rhomboideus muscular complex of the llama. in this study, the authors describe the length, insertions, and inervation of the rhomboideus suprascapular muscle of the llama in order to define it as another portion of the rhomboideus muscular complex. moreover, the forenamed muscle is proposed as a scapular elevator.
