GROSS ANATOMY

Detailed explanation-1: -Pronation and supination are movements that occur at the proximal radioulnar joint. The head of the radius is discoid and fits with the radial neck within the circular annular ligament, that attaches the proximal radius to the ulna.

Detailed explanation-2: -Pronation and Supination Pronation describes a rotational movement of the forearm that results in the palm facing posteriorly (when in the anatomic position). Supination describes the motion of turning the palm anteriorly (Fig. 1.14).

Detailed explanation-3: -Your wrist is an extension of your forearm. It can’t supinate or pronate on its own. Supination and pronation of the arm come from arm movement, not wrist movement. Specific wrist movements includes flexion, extension, and side-to-side movement of the hand.

Detailed explanation-4: -In the upper limb, pronation is the rotatory movement during which the palm and forearm face downward. The forearm is the part of the upper limb below the elbow joint. It has two bones: radius and ulna. Two joints are involved in pronation and supination of the hand and forearm.

Detailed explanation-5: -Human hand pronation-supination movement is accomplished by movement of the radius and ulna bones relative to each other via the complex proximal and distal radioulnar joints, each with multiple degrees of freedom (DOFs).
