Subclavius muscle

It arises by a short, thick tendon from the first rib and its cartilage at their junction, in front of the costoclavicular ligament. from manubrium to clavicle between pectoralis major and coracoclavicular fascia. ==Function==

It depresses the lateral clavicle, acts to stabilize the clavicle while the shoulder moves the arm. It also raises the first rib while lowering the clavicle during breathing. The subclavius protects the underlying brachial plexus and subclavian vessels from a broken clavicle—the most frequently broken long bone. ==Additional images==
