Supination and Pronation

Supination - In semiflexed elbow, the palm is turned upward. It is more powerful than pronation because it is an antigravity movement.
Movements- all screwing movements of hand, e.g. As in tightening nuts and bolts.
It is brought by supinator & biceps brachii.


Pronation - In semiflexed elbow, the palm is turned downward. It is brought about chiefly by pronator quadratus. Aided by pronator teres while rapid movement and against resistance




These are the rotatory movements of the forearm around vertical axis
The axis is not stationary because the lower end of ulna is not fixed - it moves backward & laterally during pronation and forwards & medially during supination.
As a result the axis is displaced laterally in pronation, and medially in supination.
