Wrist ABduction: Synergist & Antagonist Muscles

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.
