What is the origin point for the pectoralis major muscle?

The pectoralis major muscle has its origin at both the clavicle and the sternum, making this option the correct choice. Specifically, the muscle originates from the medial half of the clavicle, the sternum, and the cartilage of the first six ribs. This anatomical structure plays a crucial role in the function of the muscle, which is primarily involved in movements such as flexion, adduction, and internal rotation of the shoulder joint.

The origins from the clavicle and sternum contribute to the muscle's ability to effectively stabilize and move the upper limb. The fibers of the pectoralis major fan out to insert into the humerus, allowing a powerful range of motion for activities like pushing or lifting. Understanding the origin of this muscle is essential for anyone studying sports massage, as it provides insights into how to manipulate and facilitate optimal movement patterns as well as target areas for massage therapy that may help alleviate tension or facilitate recovery.
