What part of the scapula articulates with the humerus?
The scapula is flat and triangular. The scapula articulates with the humerus at the glenoid fossa and the clavicle at the acromion process.
What muscles connect to the scapula?
The intrinsic muscles of the scapula include the rotator cuff muscles, teres major, subscapularis, teres minor, and infraspinatus. These muscles attach the scapular surface and assist with abduction and external and internal rotation of the glenohumeral joint.
