Tenodesis grasp and release is an orthopedic observation of a passive hand grasp and release mechanism, affected by wrist extension or flexion, respectively.It is caused by the manner of attachment of the finger tendons to the bones and the passive tension created by two-joint muscles used to produce a functional movement or task (tenodesis).

A gyroscopic wrist exerciser. Video showing the use - from starting the rotation with a 'shoestring' over various movements with the holding hand until stopping the rotor with the second hand. The demonstrated speeds are, in part, very high and not recommended for normal exercise due to the resulting high forces.
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.

The exercises are divided in three parts: Exercises 1 - 20: Labeled "preparatory exercises", these are also the most famous exercises, and are used to develop finger strength and independence. Each exercise contains a sequence of 8 semiquavers, beginning on C, which is then repeated starting on D, and so on across two octaves. The exercise is ...
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 ...
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 ...
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
