Describe five joints found in the upper limb????

1. Shoulder joint: Also known as the glenohumeral joint, this is a ball-and-socket joint that connects the humerus (upper arm bone) to the scapula (shoulder blade). It allows for a wide range of motion in the arm, including flexion, extension, abduction, adduction, and rotation.

2. Elbow joint: This is a hinge joint formed by the articulation of the humerus with the ulna and radius bones of the forearm. It allows for flexion and extension of the arm.

3. Radioulnar joints: There are two radioulnar joints in the upper limb - the proximal radioulnar joint and the distal radioulnar joint. These joints allow for rotation of the forearm, which is important for activities such as turning a doorknob or using a screwdriver.

4. Wrist joint: Also known as the radiocarpal joint, this is a condyloid joint that connects the radius and ulna to the carpal bones of the wrist. It allows for flexion, extension, abduction, and adduction of the hand.

5. Carpometacarpal joints: These are the joints that connect the carpal bones of the wrist to the metacarpal bones of the hand. They allow for movement and flexibility in the hand, particularly in activities that involve grasping and manipulating objects.
