Questions: Which of the following is not a muscle that moves the forearm? pronator quadratus brachialis supinator pronator teres teres major

The answer is the last one (teres major): the original text in the question...

Explanation for each option:

1. Pronator quadratus: This is a muscle that moves the forearm. It is responsible for pronating the forearm, which means turning the palm downward.

2. Brachialis: This muscle also moves the forearm. It is a primary flexor of the elbow, meaning it helps to bend the elbow joint.

3. Supinator: This muscle moves the forearm by supinating it, which means turning the palm upward.

4. Pronator teres: This muscle is involved in moving the forearm as well. It helps in pronating the forearm.

5. Teres major: This muscle does not move the forearm. It is located in the shoulder region and is involved in the movement of the humerus (upper arm bone), specifically in adduction and medial rotation of the arm.

Summary: The teres major is not a muscle that moves the forearm.
