When flexing the elbow, the biceps brachii, brachioradialis, and brachialis are the three major agonists recruited to perform this movement because all cause flexion at the elbow. However, the biceps also cause supination, an undesired movement. Therefore another muscle acting as a ________, causing ________ must be recruited to prevent the undesired motion.

Respuesta :

Answer:

neutralizer , pronation.

Explanation:

Supination is an anatomical term related to the rotational motion of the foot or the forearm.

Pronation is also same as the supination but the direction of rotation of pronation is opposite to supination.

So to neutralize the supination the another muscle rotates in opposite direction means pronation to prevent the undesired motion of the bicep.
