Inter- and Intraspecific Variations in the Pectoral Muscles of Common Chimpanzees (Pan troglodytes), Bonobos (Pan paniscus), and Humans (Homo sapiens)

<div>(a) Dissection of a Homo sapiens. We can see the insertion of the pectoralis minor in the glenohumeral capsule. Pm (pectoralis minor), CP (coracoid process), GHC (glenohumeral capsule), and ST (supraspinatus tendon). (b) Histological cross section showing the insertion of the pectoralis minor tendon in the glenohumeral capsule in a Homo sapiens. Pm (pectoralis minor) and GHC (glenohumeral capsule).</div>
