The hand is a delicate and complicated structure with 27 bones, 34 muscles, 29 joints, 48 named nerves (3 major), 30 named arteries, and over 123 ligaments. Because of this complexity, one quarter of the brain's motor cortex controls the muscle movements of the hand.
Interesting notes about the hand:
