Question

Name the flexor muscle that acts in wrist flexion and radial deviation.

a) Flexor carpi radialis
b) Flexor carpi ulnaris
c) Extensor carpi radialis longus
d) Extensor carpi radialis brevis

Answer 1

The flexor muscle responsible for acting in wrist flexion and radial deviation is the flexor carpi radialis, which flexes and abducts the hand at the wrist.

Step-by-step explanation:

The flexor carpi radialis is the muscle that acts in wrist flexion and radial deviation. This muscle flexes and abducts the hand at the wrist, thereby decreasing the angle at the joint. It is one of the muscles in the anterior compartment of the forearm that originates from the medial epicondyle of the humerus and inserts into the hand to facilitate movements of the wrists, hands, and fingers. The flexor carpi radialis is distinguished from the flexor carpi ulnaris, which instead flexes and adducts the hand at the wrist.
