Study Notes
Upper Limb Anatomy
- The wrist is supported by 8 carpal bones.
- Each finger has 3 phalanges, except for the thumb, which has only 2.
- The exclusive movement of opposition is permitted in the thumb, allowing it to touch the other fingers.
Hand Movement
- The movements of the second to fifth digits are permitted in the metacarpophalangeal joints.
Shoulder Girdle
- The shoulder girdle is made up of the scapula and clavicle.
- The joint where the clavicle articulates with the axial skeleton is called the sternoclavicular joint.
- The humerus meets the scapula to form the shoulder joint, also known as the glenohumeral joint.
Elbow Joint
- The elbow joint permits flexion, extension, and rotation of the forearm.
Radioulnar Joints
- The radioulnar joints permit pronation and supination of the forearm.
Forearm Movement
- During supination, the palm faces anteriorly, while during pronation, the palm faces posteriorly.
