Study Notes
Synergist Muscles for Wrist ABduction
- Extensor carpi radialis longus: A key muscle aiding in the radial deviation of the wrist.
- Extensor carpi radialis brevis: Works in conjunction with other synergists to assist in wrist abduction.
- Extensor pollicis longus: Contributes to the motion by extending the thumb, also influencing wrist movement.
- Extensor pollicis brevis: Assists in both thumb extension and wrist abduction.
- Flexor carpi radialis: A flexor that also supports wrist abduction by moving the wrist towards the thumb side.
- ABductor pollicis longus: Specifically targets thumb movement and complements wrist abduction.
Antagonist Muscles for Wrist ABduction
- Extensor carpi ulnaris: An antagonist that opposes wrist abduction by facilitating ulnar deviation.
- Flexor carpi ulnaris: Works against wrist abduction, promoting movement towards the ulnar side of the forearm.
