Final answer:
The Pectoralis Minor is attached from the anterior surfaces of the third to fifth ribs and to the coracoid process of the scapula, aiding in scapular movement and stabilization.
Step-by-step explanation:
The Pectoralis Minor muscle is a critical component of the pectoral girdle that attaches the upper limb to the axial skeleton. Specifically, the Pectoralis Minor originates from the anterior surfaces of the third to fifth ribs near their costal cartilages and attaches to the medial border and superior surface of the coracoid process of the scapula. This muscle plays a role in the movement and stabilization of the scapula, assisting with actions such as scapular depression, protraction, and downward rotation.
