Relating to the shoulder joint, which connects the glenoid cavity of the shoulder blade to the head of the arm bone.
From 'glenoid' (Greek 'glene' = socket, 'eidos' = form) and 'humeral' (from Latin 'humerus' = arm bone). The compound term describes the joint between these two bone parts.
Your glenohumeral joint is one of the most mobile joints in your entire body—so mobile that it's actually prone to dislocation more easily than almost any other joint, which is why professional athletes train to stabilize it!
