Verified step by step guidance

1. Step 1: Understand the anatomy of the clavicle. The clavicle, or collarbone, is a long bone that connects the arm to the trunk of the body. It has two ends: the medial end (sternal end) and the lateral end (acromial end), as well as a shaft in the middle.
2. Step 2: Learn the function of the acromial end. The acromial end is the lateral end of the clavicle that articulates with the acromion of the scapula, forming part of the acromioclavicular joint.
3. Step 3: Differentiate the medial end from the lateral end. The medial end of the clavicle articulates with the sternum at the sternoclavicular joint, while the lateral end articulates with the scapula.
4. Step 4: Recognize the middle shaft of the clavicle. The shaft is the elongated middle portion of the clavicle, which does not directly articulate with other bones but serves as an attachment site for muscles and ligaments.
5. Step 5: Identify the inferior surface of the clavicle. The inferior surface contains grooves and ridges for ligament and muscle attachment but is not referred to as the acromial end.
