Abduction, in asana movement.

Abduction of a joint makes a body part move away from the midline of the body in the anatomical position. For instance, abduction is the term used for the movement made, and not for the position of the hands at a particular point. Same goes with the legs: Moving of the legs away from the midline, as one spreads one’s legs out to any possible degree is known as abduction of the legs.
