No.
The biceps are a flexor muscle.
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.
No, your bicep is a muscle.
An extensor straightens part of your body.
Extensor digiti minimi, extensor digitorum longus, and extensor hallucis.
A torn bicep muscle can usually occur when your bicep muscle is fully extended and under too much pressure. Weight lifters often get a torn bicep muscle when doing the preacher curl. The preacher curl can really strain the bicep muscle, and lead to a torn bicep muscle if you are lifting to much weight or have not warmed up correctly. Your bicep is a muscle on your arm. it is the muscle that you usually flex when trying to show off your srength. Most torn bicep muscle injuries occur when the arm is fully extended and the lifter is just about to pull the weight back up. When you get a torn bicep muscle you will feel an immediate sharp pain in your bicep near your elbow, followed by bicep muscle weakness and stiffness and eventaully bruising.
Extensor digitorum longus, extensor hallucis longus and extensor digitorum brevis
The bulk of the muscle is proximal. But part of it isn't.
The bicep muscle. The tricep contracts to straighten the arm as the bicep relaxes.
The triceps are extensor muscles.
What you are talking about is flexor muscle and not extensor aren't you?
There are two: the extensor digitorum (toes) brevis muscle and the extensor hallucis (big toe) brevis muscle.
extensor digitorum
