Origin: Lateral anterior surface of ribs 1-9
Insertion: Anterior surface medial margin of scapula
Which muscle forms the anterior wall of the Axilla?
Which muscle is active in Forced Breathing?
What are the origin and insertion points of Pect Minor?
Origin: Sternal ends of ribs 3-5
Insertion: Coracoid process of Scapula
What is the function of the subclavius muscle?
It performs downward rotation and stabilizes the clavicle
