Anatomy of the Clavicle

The clavicle is part of the skeleton of the shoulder girdle, linking the sternum and scapula. It is a long, flat, subcutaneous bone that can be palpated under the skin.

The clavicle has two faces and two borders, with insertions for muscles such as the deltoid and trapezoid on its surfaces. The video explores the upper and lower surfaces, and anterior and posterior borders.

The clavicle is a key site for muscular attachment, including muscles such as the sternocleidomastoid and subclavius. Ligaments like the conoid and trapezoid attach to specific tubercles on the clavicle.

The clavicle's sternal end articulates with the sternum and first costal cartilage, while the acromial end articulates with the acromion of the scapula.

The clavicle consists of superficial compact bone and deeper spongy bone, with a medullary canal developing in its middle third.
