The muscles of the forearm can be divided into two main groups: the pronators and supinators. The pronators are responsible for rotating the forearm, bringing the palm of the hand downwards, while the supinators are responsible for rotating the forearm, bringing the palm of the hand upwards.

The wrist consists of eight small carpal bones acting as a flexible bridge to the metacarpals. The mechanical pivot for wrist movement sits lower than most artists realize—right at the base of the palm, rather than where the forearm meets the hand.

The hand is controlled by a complex system of intrinsic and extrinsic muscles. Intrinsic muscles, such as the thenar and hypothenar muscles, control finger movement, while extrinsic muscles, such as the flexor digitorum profundus and extensor digitorum communis, control hand and finger movement. The mechanical pivot for wrist movement sits lower
