explain this briefly.
Dear student
Flexor - A movement that decreases the angle between two bones at the joint.
Extensor - A movement that increases the angle between two bones at the joint.
Abductor - A movement that results in the part moving away from the midline.
Adductor - A movement that results in the part moving towards the midline.
Protractor - an instrument for measuring angles.
Supinator - a muscle whose contraction produces or assists in the supination of a limb or part of a limb.
Elevator - movement in a superior direction.
Depressor - to pull the corners of the mouth down and back, which produces a frown. (Inferior direction)
Protractor is not a muscle. So the correct option is Protractor : Supinator.
