Coracobrachialis

Scapulohumeral muscle of the shoulder girdle: the frontal abductor originating mostly approximately together with the short head (caput breve) of the arm biceps.
Classically, the coracobrachialis is described as a monoarticular single-headed muscle. According to a more recent study, this is much less uniform: only in just under 50% the muscle originates with a single head as usually described medioposterior to the short head of the biceps, but in 43% it has two heads, which either both originate from the processus coracoideus, or one of them originates from the cranial short head of the biceps. In just under 8% of cases, there were even three heads, two of which arise from the processus coracoideus and the third from the short head of the biceps.
Origin: mostly (see above) coracoid process of the scapula
Attachment: Inner side of the humerus, opposite the deltoid tuberosity
Antagonists: …
Movement: Fixation of the humerus in the hip socket (acetabulum), lateral adduction, frontal abduction, endorotation of the arm
Strengthening postures (232): Postures with powerful frontal abduction such as upface dog, three-point headstand
Stretching postures (231): Postureswith retroversion such as purvottanasana, setu bandha sarvangasana, sarvangasana, uttanasana, prasarita padottanasana with arms behind the back
