However, the intrinsic muscles of the hand are only partially responsible for all its range of motion. The other major contributors are actually the forearm muscles, which project tendons towards the hand via an equally complex and flexible anatomical structure, called the wrist. A solid ...
In vivo forces in one or both flexor tendons have been measured and reported during active and passive motion of the fingers and wrist (1, 2). However, the influence of finger and wrist joint positions on the amount of force generated during active finger flexion was not assessed. The go...
Sonography of the finger flexor and extensor system at the hand and wrist level: findings in volunteers and anatomical correlation in cadavers We present a review of sonography of the flexor and extensor system of the hand and wrist in volunteers and cadavers. CT tenography also was performed in...
Both the extensor carpi radialis longus and extensor carpi radialis brevisextend your wrist and move your hand away from the direction of your thumb. The extensor digitorum splits into four tendons and connects to the finger joints. It helps you straighten or extend your fingers. ...
Wrist and Hand In the carpal tunnel, the median nerve may be compressed by accessory muscles, such as abnormal or hypertrophied lumbricals, variant flexor digitorum superficialis tendons, and palmaris longus or palmaris profundus muscles (De Smet, 2002). Variant muscles may compress the ulnar ner...

Muscles are attached to bones via tendons or aponeuroses and receive a rich nerve supply to allow precise movement control. The structural unit of a muscle is the muscle fiber, while the functional unit is a motor unit. Skeletal muscles mostly act in antagonism, meaning that when one ...

There are no muscles “in” your hand, only tendons, ligaments, and bones. Your fingers move when your forearm muscle pulls on those other connective tissues. Your eye muscles move over 100,000 times a day, most rapidly during deep sleep. The one muscle that is working every second of ev...
