While this field of study has now become tightly bound up with …
Subclavius is a small muscle that arises from the costochondral junction of the first rib and is inserted into the subclavian groove on the inferior surface of the clavicle. Together with the pectoralis major and pectoralis minor, the subclavius form the anterior wall of the axilla. Subclavius Origin and Insertion The subclavius muscle originates by …
Pectoralis minor is also called P. minor and it is a triangular muscle that lies in the anterior wall of the axilla and is almost completely covered by the pectoralis major. Pectoralis minor attachments and boundaries Pectoralis minor is origin is from the 3rd to 5th ribs near their costal cartilages, while its insertion is …
Pectoralis Major is a muscle that forms part of the pectoral girdle and also helps in its movement. There are other pectoral muscles that form the pectoral girdle and these muscles (pectoralis major, pectoralis minor, subclavius, and serratus anterior) will be discussed individually; these four (4) muscles form the anterior axioappendicular (thoracoappendicular or pectoral) …
