Bony anatomy of the shoulder

The humerus

The humeral head is the "ball" part of the ball and socket. It is made up 4 of components:Rounded joint surface

Atuberosity is a distinct prominence or bump on a bone which is usually where a muscle or a ligament attaches.

Atuberosity is a distinct prominence or bump on a bone which is usually where a muscle or a ligament attaches.

ΩThere are two of these on the humerus, the greater tuberosity and the lesser tuberosity.

Ω The greater tuberosity is the site of insertion for three important shoulder (rotator cuff) muscles; the supraspinatus, infraspinatus and teres minor.

Ω The lesser tuberosity is the site of subscapularis insertion which is another shoulder muscle.

Ω bicipital groove is the groove between the greater and lesser tubercles. The groove functions as a passage for the tendon of the long head of the biceps brachii.

The scapula (shoulder blade)

Ω The scapula (commonly known as the shoulder blade) is a triangular shaped bone which has a part called the glenoid that forms the "socket" for the head of the humerus.

The clavicle (collar bone)
