<P> The pectoralis minor muscle is covered anteriorly (superficially) by the clavipectoral fascia . The Medial pectoral nerve pierces the pectoralis minor and the clavipectoral fascia . In attaching to the coracoid process, the pectoralis minor forms a' bridge' - structures passing into the upper limb from the thorax will pass directly underneath . </P> <P> Axillary nodes are classified according to their positions relative to the pectoralis minor muscle . Level 1 are lateral, Level 2 are deep, Level 3 are medial . The pectoralis minor divides the axillary artery into three parts (in contrary sequence compared to the nodes) - first part medial, second part deep / posterior, third part lateral in relation to the pectoralis minor . </P> <P> The origin is from the second, third and fourth or fifth ribs . The tendon of insertion may extend over the coracoid process to the greater tubercle . It may be split into several parts . Absence of this muscle is rare but happens with certain uncommon diseases, such as the Poland syndrome . </P> <P> The pectoralis minor depresses the point of the shoulder, drawing the scapula inferior, towards the thorax, and throwing its inferior angle posteriorly . </P>
