Human hands are the two prehensile body parts, each with four fingers and one thumb, located at the far end of each arm. They are used for a wide range of tasks from the roughest motor skills (wielding a club) to the finest (threading a needle). Many tasks require learned hand-eye coordination where movement is controlled by the brain which receives visual information from the eyes, tactile sensation from nerve endings in the skin including the fingertips, and joint position sense from nerves around joints. Note that arteries and nerves have not been drawn in across the middle of the hand and palm to show the deeper layers.
