extensor
Triceps muscle is not a flexor. Triceps is an extensor of elbow joint. Biceps muscle is flexor.
The triceps are extensor muscles.
Extensor muscles open a joint and are the opposite to flexor muscles, which close it. I imagine triceps are extensor, while biceps are flexor.

extensorThe triceps brachii is an extensor. It is the large muscle on the back of the arm and is primarily the muscle used for extension of the elbow joint or straightening of the arm. The triceps is also an antagonist of the biceps and the brachialis muscles.ExtensorsTriceps is not a flexor. It is extensor of the elbow joint.
Extensor
Triceps brachii and the anconeus attach to the olecrannon process. The pronator quadratus originates at the anteriodistal end for the ulna. The supinator, extensor pollicis longus and brevis, abductor pollicis longus, and extensor indicis all originate on the ulna.
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.
no it isnt because the arm is bent by the flexor muscles (mostly just the biceps), and straightened by the extensor muscles (ie. the triceps).
