The human shoulder is made up of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone) as well as associated muscles, ligaments and tendons.
The labrum is a second kind of cartilage in the shoulder which is very different from the articular cartilage. All together it is made up of four joints as well as the muscles that are responsible for movement in the shoulder attached to the scapula, humerus and the clavicle. The rotator cuff muscles are a collection of muscles and tendons that surround the shoulder, giving it support and allowing its wide range of motion. To turn medical or anatomical matter into a helpful visual for any project please contact Medical Artist Joanna.
The shoulder has the full range of motion from adduction, abduction, flexion, extension, internal rotation, external rotation, and 360 degree circumduction in the sagittal plane.
