Question
Identify the muscles that rotate (pronate or supinate) the
forearm.
Expert Solution
Step 1
Muscles are soft and contractile tissues of the body. These tissues are principally responsible for allowing the body's movement as actin and myosin slide over each other.
Step 2
The muscles responsible for rotating the forearm are the biceps brachii which functions with the supinator muscle for forearm rotation when the palm faces upward. The pronator teres and quadratus are the muscles that control the rotation of the forearm when the palm faces downward.
