The bones of the hand and wrist provide the body with support and flexibility to manipulate objects in many different ways. Each hand contains 27 distinct bones that give the hand an incredible range and precision of motion.

The dorsal digital expansion permits the long digital flexors and the short muscles of the hand to act on all three finger joints. Muscle Facts (I) The intrinsic muscles of the hand are divided into three groups: the thenar, hypothenar, and metacarpal muscles (see p. 314 ).

2023年11月13日 · Hand (dorsal view) The human hand, the most distal part of the upper limb, is a remarkable feat of engineering and evolution. It is strong enough to allow climbers to tackle any mountain, but also sufficiently precise for the manipulation of some of the world’s smallest objects and the performance of complex actions.
