Shoulder
Regio deltoidea (humerus) · Rameno
Joints & cartilage
Looks like
A shallow ball-and-socket held by four cuff muscles, with the collarbone as the only bony link to the trunk.
What it does
The freest joint in the body — it puts the hand anywhere.
Keeping it well
Cuff and shoulder-blade exercises, avoid heavy overhead work when sore. It dislocates because it trades stability for range.
