What is the distal attachment point of the subclavius muscle?

• A. Inferior surface of the scapula
• B. The middle of the inferior surface of the clavicle
• C. Greater tubercle of the humerus
• D. Rib 1

Answer: (B)

The subclavius muscle is a small muscle located beneath the clavicle. Its primary role is to stabilize the clavicle during shoulder movements and assist in the movement of the shoulder girdle. The distal attachment point of the subclavius is specifically on the middle of the inferior surface of the clavicle. This anatomical relationship allows the muscle to effectively perform its function of stabilizing the clavicle, especially during activities that involve the upper limb. Understanding the attachment points of the subclavius is vital for comprehending its role in shoulder mechanics and the implications that may arise from injury or dysfunction in this area. For example, if the subclavius is compromised, it could impact the alignment and stability of the entire shoulder joint.
