Question
The pronator quadratus assists the pronator teres in ______.
- extending the arm
- rotating the arm medially
- rotating the arm laterally
Solution
The pronator quadratus assists the pronator teres in rotating the arm medially.
Both muscles are primarily involved in the action of pronation, which is the movement that turns the palm of the hand downward or backward. While the pronator teres is more superficial and assists in flexing the elbow, the pronator quadratus plays a crucial role in the pronation of the forearm, working along with the pronator teres to ensure effective medial rotation of the arms during this movement.
Thus, the correct answer to the question is "rotating the arm medially."
