Description For description of anatomical structures in the hand, it is important to know that the anatomical position of the hand is hanging alongside the trunk with fingers pointing downward and the palm pointing forward (Figure 2.1). Hand represents the utmost peripheral part of the upper extremity. In humans, it accomplishes fine movements incomparable with other species, like monkeys, which use their hands for handling items and performing simple movements. In contrast, human hand is able to perform the most intricate movements—for example see piano players, whose hands smoothly and quickly change among all sorts of the movements in numerous joints forming their hands: flexion, extension, abduction, adduction, circumduction, pronation and supination. It is a concert of movements parallel to the concert of sounds. Bones, bound together by joints and operated by muscles, represent the structural conditions for performing these movements. Proper function is ensured by appropriate blood flow in the hand muscles. Blood flow in the hand skin plays moreover a crucial role in control of body temperature.
