1 lut 2017 · Proper functioning of the hand relies on its capacity to rotate and point the palm upward (i.e. supination) or downward (i.e. pronation) when standing up with the elbow in 90° flexion. Hand rotation is possible because of forearm rotation and also rotation of the whole upper limb at the shoulder.
The hand, positioned at the end of the upper limb, is a combination of complex joints whose function is to manipulate, grip and grasp, all made possible by the opposing movement of the thumb. [3] Some biologists believe that the development of the human hand lead indirectly to the development of our large and complex brain.

Supination and pronation of the hand are rotational movements which occur at the superior radioulnar joint. These rotational movements are facilitated due to the presence of an annular ligament which holds the upper end of the radius in close apposition with the ulna.
Introduction. The hand contains a number of joints that allow complex actions, such as manipulating, gripping and grasping objects. Optimal hand function requires adequate strength, sensation, range of motion, and dexterity.
