The radiocarpal joint allows for a wide range of movements, including: Flexion: Bending the hand toward the palmar side. Extension: Bending the hand away

in that they aren't innervated by the ulnar nerve: the abductor (Ab) and flexor (F) pollicis brevis, opponens pollicis (O), and lateral lumbricals (Law)

This type of joint is biaxial because it permits two axes of movement: flexion/extension and medial/lateral (abduction/adduction). An example is the metacarpophalangeal

motor control tasks. The flexor carpi ulnaris is the most powerful wrist motor and tends to place the wrist in a position of flexion and ulnar deviation. The
