Extensor
extensor
Extensor muscles open a joint and are the opposite to flexor muscles, which close it. I imagine triceps are extensor, while biceps are flexor.
There's more than one: flexor carpi radialis palmaris longus flexor carpi ulnaris pronator teres flexor digitorum superficialis (sublimis) flexor digitorum profundus flexor pollicis longus pronator quadratus brachioradialis extensor carpi radialis longus extensor carpi radialis brevis extensor digitorum (communis) extensor digiti minimi (proprius) extensor carpi ulnaris abductor pollicis longus extensor pollicis brevis extensor pollicis longus extensor indicis (proprius) supinator anconeus
extensor digitorum, extensor indicis, extensor digiti minimi, flexor digitorum superficialis, and the flexor digitorum profundus. There are also extrinsic muscles that work only in the thumb; these include the flexor pollicis longus, extensor pollicis longus, extensor pollicis brevis, and adbuctor pollicis longus
All skeletal muscles will have a flexor and an extensor. The flexor bends the joint. The extensor straightens it out again.
The muscles of the legs do not follow the generalization that extensor muscles are on the posterior and flexor muscles are on the anterior.
Triceps muscle is not a flexor. Triceps is an extensor of elbow joint. Biceps muscle is flexor.
Yes. Skeletal muscles will have a flexor and an extensor. The flexor bends the joint. The extensor straightens it out again.
There are many muscles in the hand. Here are a few: extensor carpi radialis brevis extensor carpi radialis longus extensor carpi ulnaris extensor digitorum communis extensor indicis proprius extensor digiti minimi abductor pollicis longus extensor pollicis brevis extensor pollicis longus flexor carpi ulnaris flexor digitorum profundus flexor digitorum superficialis flexor carpi radialis flexor carpi ulnaris palmaris longus flexor pollicis longus abductor pollicis brevis flexor pollicis brevis opponens pollicis adductor pollicis palmaris brevis abductor digiti minimi flexor digiti minimi opponens digiti minimi Then each finger has a set of lumbrical muscles and 3 volar and 4 dorsal muscles
The triceps are extensor muscles.
What you are talking about is flexor muscle and not extensor aren't you?
