The wrist curl is a weight training exercise for developing the wrist flexor muscles, the muscles in the front of the forearm. [1] It is therefore an isolation exercise. Ideally, it should be done in combination with the "reverse wrist curl" (also called wrist extension) which works out the muscles comprising the back of the forearms, [1] to ensure equal development of the wrist flexor and ...
The extensor carpi radialis longus is a wrist extensor that is innervated by the radial nerve, [2] [3] from spinal roots C6 and C7. [4] All other major extensor muscles in the superficial layer of the posterior compartment (the extensor digitorum , extensor carpi radialis brevis , extensor carpi ulnaris , and extensor digiti minimi ) are ...
The radial nerve innervates the finger extensors and the thumb abductor; that is, the muscles that extend at the wrist and metacarpophalangeal joints (knuckles) and abduct and extend the thumb. The median nerve innervates the flexors of the wrist and digits, the abductors and opponens of the thumb, the first and second lumbricals. The ulnar ...
Joints of the hand, X-ray. The bones in each carpal row interlock with each other and each row can therefore be considered a single joint. In the proximal row a limited degree of mobility is possible, but the bones of the distal row are connected to each other and to the metacarpal bones by strong ligaments that make this row and the metacarpus a functional entity.
In human anatomy, the wrist is variously defined as (1) the carpus or carpal bones, the complex of eight bones forming the proximal skeletal segment of the hand; [1] [2] (2) the wrist joint or radiocarpal joint, the joint between the radius and the carpus [2] and; (3) the anatomical region surrounding the carpus including the distal parts of the bones of the forearm and the proximal parts of ...
In anatomy, flexor carpi radialis is a muscle of the human forearm that acts to flex and (radially) abduct the hand. The Latin carpus means wrist; hence flexor carpi is a flexor of the wrist. Origin and insertion
The mobile wad (or mobile wad of Henry) is a group of the following three muscles found in the lateral compartment of the forearm: [1]. brachioradialis; extensor carpi radialis brevis
It is an extensor, and an abductor of the hand at the wrist joint. That is, it serves to manipulate the wrist so that the fingers moves away from the palm. The muscle, like all extensors of the forearm, can be strengthened by exercise that resist its extension; Reverse wrist curls with dumbbells can be performed.
