When bones attached to a muscle are connected by a flexible joint, contraction of the muscle moves the skeleton. The muscle is called a flexor if the centers of the connected bones are brought closer together when the muscle contracts, and the movement is called flexion. (Biceps)

The muscle is called an extensor if the bones move away from each other when the muscle contracts, and the movement is called extension. (Triceps)

Extensor digitalis longus and extensor digitalis lateralis and a couple othersEdit: The answer above is incorrect. Extensor Digitalis Longus doesn't exist, they may have been thinking about the digitorum which, even so, is in the lower part of the body.-When flexing the fingers (moving the fingers toward the palm) a number of different muscles are being used for each finger.-Regarding the Thumb: Flexor pollicis brevis, Abductor pollicis brevis, Adductor pollicis brevis, extensor pollicus longus and Opponens pollicis are being used.-Regarding the first finger: 1st dorsal interosseous, 1st palmar interosseous and Flexor digitorum profundis/superficialis. --Regarding the second finger: 2nd dorsal interosseous, 2nd palmar interosseous and Flexor digitorum profundis/superficialis.And if you are taking into consideration the flexion of the wrist when writing you may want to include: flexor carpus radialis, flexor carpus ulnaris, and palmaris longus.These muscles should account for all movement, but if you find any extras feel free to edit this post further.-Anticipated Degree B.S. in Athletic Training, May 2017
