Adduction
Adduction (from latin adducere , introduce ' ) is in the physiology of the pre-guiding of a body portion of the body or limbs axis. Thus those muscles are referred to as adductors which allow the longitudinal axis of a limb to be shifted to the plane of the longitudinal axis of the body.
Adductor injuries are common sports injuries .
Movement examples:
- A splayed leg is pulled straight under the body.
- A parked arm is pulled towards the body.
- Spread toes are pulled together again.
- Tightening the splayed thumb at hand
At the 3-axis ball joints such as the hip joint or shoulder joint , the main movement takes place around the sagittal = dorsoventral main axis.
In ophthalmology , adduction refers to the inward turning of the eyeball towards the nose due to a contracture of the rectus medialis muscle . If both eyes are adducted at the same time, this is called convergence .
