The human hand the most distal part of the upper limb is a remarkable feat of engineering and evolution. The thumb doesnt have a middle phalanx. The palm includes five metacarpals and each finger except the thumb contains one proximal phalanx one middle phalanx and one distal phalanx.

The hands enable us to perform many of our daily activities such as driving writing and cooking. Hand anatomy the human hand is made up of the wrist palm and fingers and consists of 27 bones 27 joints 34 muscles over 100 ligaments and tendons and many blood vessels and nerves.
