Coracobrachialis Muscle: Key to Shoulder Stability and Injury Prevention

The coracobrachialis, a long, thin muscle, plays a crucial role in shoulder joint stability. It draws the arm forward and pulls it towards the body's midline. This muscle originates from the coracoid process of the scapula and inserts midway along the inside of the humerus. It's innervated by the musculocutaneous nerve and supplied with blood by the brachial artery's muscular branches. Overuse, particularly during exercises like bench pressing, can result in injury to this muscle. The coracobrachialis is vital for shoulder joint function and stability. Understanding its role and potential for injury can help prevent issues and maintain overall shoulder health.
