When ARM flexes which muscle contracts quizlet?

When the biceps brachii muscle contracts (elbow flexion), the forearm moves toward the humerus.

What is flexion of the elbow?

When your forearm moves toward your body by bending at your elbow, it’s called elbow flexion. The opposite movement is called elbow extension. The three bones involved in elbow flexion are the: humerus, in your upper arm. ulna, on the little finger side of your forearm.

Where is the biceps?

The biceps muscle is located at the front of your upper arm. The muscle has two tendons that attach it to the bones of the scapula bone of the shoulder and one tendon that attaches to the radius bone at the elbow. The tendons are tough strips of tissue that connect muscles to bones and allow us to move our limbs.

What muscles flex the elbow?

What is the prime mover of the elbow?

Elbow Flexors

The prime movers of elbow flexion are the biceps brachii, the brachialis, and the brachioradialis. These muscles have a line of force that passes anterior to the elbow’s axis of rotation (Fig. 5.19). The pronator teres is considered a secondary elbow flexor.
