The pectoralis major is a muscle of the upper limb girdle. This muscle has a unique morphological architectonic and a high rate of clinical applications. However, there is lack of data regarding the morphological and functional interactions of the pectoralis major with other muscle and fascial compartments. According to the applied knowledge, the “Humero-pectoral” morpho-functional concept has been postulated. The purpose of this review was the dissectible investigation of the muscle anatomy and literature review of surgical applications
