Most freely movable, loose and thin capsule, glenoid labrum: supported by ligaments, tendons, muscles. Shoulder is stabilized mainly by the biceps
Stabilizers of the shoulder joint
Weak and absent
Extends from coracoid of scapula to greater tubercle of humerus
Extends from the greater to lesser tubercle
of the humerus forms a tunnel housing the tendon from long head of the biceps
Small synovial sacs between tendons and bones, allowing them to slide more easily past each other
Encircle tendon that pass through the palm of the hand
Formed by the articulation of:
-Femur & Os Coxae

deep socket: acetabular labrum
transverse: acetabular ligament
