Abduction (kinesiology)

Abduction, in functional anatomy, is a movement which draws a limb away from the median (Sagittal) plane of the body. It is thus opposed to adduction.

Upper limb

 * Flexor carpi radialis
 * Extensor carpi radialis longus
 * Extensor carpi radialis brevis
 * Abductor pollicis longus
 * Extensor pollicis longus
 * Extensor pollicis brevis


 * of finger
 * Abductor digiti minimi
 * Dorsal interossei of the hand


 * of thumb
 * Abductor pollicis longus
 * Abductor pollicis brevis

Lower limb

 * of femur at hip
