Which is an eccentric function of the extensor carpi radialis longus?
A)restrains/slows radial deviation (abduction)of the hand at the wrist joint
B)restrains/slows ulnar deviation (adduction)of the hand at the wrist joint
C)restrains/slows extension of the hand at the wrist joint
D)restrains/slows extension of the arm at the glenohumeral joint

Question

Quizplus · Accepted Answer

The extensor carpi radialis longus is involved in restraining or slowing down ulnar deviation (adduction) of the hand at the wrist joint, making it an eccentric function. It is responsible for extending the wrist joint and abducting the hand as a concentric function. It is not involved in restraining or slowing down radial deviation, nor does it have any role in extension of the arm at the glenohumeral joint.
