What causes your arm to bend?
The bicep contracts while the tricep relaxes
Which muscles contract when forearm is flexed at the elbow?
Both the tricep and the bicep are muscles which control rotational movement at the elbow. The bicep contracts when the forearm is flexed, and the tricep contracts when the forearm is extended.
What does a bicep do?
flex the elbow
What happens to the biceps when muscle contracts?

What movement is involved in a bench press?
horizontal adduction extend elbow
What muscle is only responsible for elbow flexion?

Which muscles flex the arm at the elbow?
The bicep flexes the arm at the elbow.
What is the prime mover muscle of shoulder horizontal adduction?
Because shoulder horizontal adduction is performed when the arm is horizontal position (i.e., the elbow is level with shoulder) and adduction is movement toward the center of the body, shoulder horizontal adduction is performed primarily by pectoralis major and anterior deltoid, with an assist by latissimus dorsi.
What do the muscles do when you straighten your arm?
Straightening your arm at the elbow is called extension. Elbow extension is caused primarily by contracting the triceps brachii muscle, although the small anconeus muscle does play a role. Wrist extension is accomplished primarily by contracting the extensor carpi radialis & the extensor carpi ulnaris; but is also assisted by contracting the extensor digitorum, the extensor indicis, the extensor digiti minimi, the extensor pollicis brevis, & the extensor pollicis longus.
What are the actions of the bicep?
Elbow flexion, shoulder flexion and supination of the forearm.
