Pectoralis minor muscle (/ ˌ p ɛ k t ə ˈ r æ l ɪ s ˈ m aɪ n ər /) is a thin, triangular muscle, situated at the upper part of the chest, beneath the pectoralis major in the human body. It arises from ribs III-V; it inserts onto the coracoid process of the scapula. It is innervated by the medial pectoral nerve.
The pectoralis major is the larger of the two, sitting on top of the smaller pectoralis minor. The pectoralis major adducts the arm, meaning it moves the limb in towards the midline of the body ...
Confirmation of the diagnosis can be done by blocking the pectoralis minor muscle or injecting botulinium.
