PA Anatomy: Limbs: Case 2

The greater tubercle or tuberosity is shown in blue and the lesser in purple. The biceps tendon runs between them, shown in orange. The AC joint is shown in yellow, with the cartilage in green. Cartilage is the same density as other soft tissues, so it shows up on radiographs as a gap between the bones of a joint.

Three tendons attach to the coracoid process, shown here. The most medial tendon is the pectoralis minor (green), and the other two are the coracobrachialis (blue) and short head of biceps brachii (pink)
