The muscles of the thumb are nine skeletal muscles located in the hand and forearm. The muscles allow for flexion, extension, adduction, abduction and opposition of the thumb. The muscles acting on the thumb can be divided into two groups: The extrinsic hand muscles, with their muscle bellies located in the forearm, and the intrinsic hand ...
Abductor pollicis brevis abducts the thumb. This muscle is the most superficial of the thenar group. Flexor pollicis brevis, which lies next to the abductor, will flex the thumb, curling it up in the palm. (The flexor pollicis longus, which is inserted into the distal phalanx of the thumb, is not considered part of the thenar eminence.)
The muscles of the hand are the skeletal muscles responsible for the movement of the hand and fingers. The muscles of the hand can be subdivided into two groups: the extrinsic and intrinsic muscle groups. The extrinsic muscle groups are the long flexors and extensors. They are called extrinsic because the muscle belly is located on the forearm ...
The EPB inserts into the base of the first phalanx of the thumb [2] to extend and abduct the thumb at the carpometacarpal and MCP joints. [5] The EPL inserts on the base of the distal phalanx of the thumb. It uses the dorsal tubercle on the radius as fulcrum [2] to help the EPB with its action as well as extending the distal phalanx of the ...
The muscle's superficial head arises from the distal edge of the flexor retinaculum and the tubercle of the trapezium, the most lateral bone in the distal row of carpal bones. [1] It passes along the radial side of the tendon of the flexor pollicis longus. The deeper (and medial) head "varies in size and may be absent."
This challenging exercise (okay, it's pretty much a workout) mashes up two sure-fire ways to build muscle—the classic 21s workout protocol, and a shifting load position by changing the ways you ...

The advantage of these dynamometers is that they to do not measure a large number of muscles in combined action, but can measure single actions such as thumb opposition of index finger abduction. [5] One such dynamometer is the Rotterdam Intrinsic Hand Myometer (RIHM). [ 6 ]
