- Hinge joints.
- Pivot joints.
- Ellipsoidal joints.
Do horses have a glenohumeral joint?
In the horse, lateral and medial movements of this joint are impossible due to the shape of the humeral head; movement is therefore limited to flexion and extension. The joint is strengthened by the medial and lateral glenohumeral ligaments.

3 joints
There are 3 joints in the carpus : the antebrachiocarpal (radiocarpal), the intercarpal (middle carpal) and carpometacarpal joint. The antebrachiocarpal and intercarpal joints are high motion joints while the carpometacarpal joint is low motion. The intercarpal and carpometacarpal joints communicate in all horses.
