What nerve innervates the flexor carpi Radialis? The median nerve provides motor innervation to the pronator teres, flexor carpi radialis, palmaris longus, and flexor digitorum superficialis.

What nerve Innervates the FCR?
The flexor carpi radialis (FCR) muscle receives innervation from the median nerve. In most limbs there is only one branch to the FCR. It arises from the lateral epicondyle of the humerus and adjacent areas.
What is flexor carpi Radialis Tendinopathy?
Summary. Flexor carpi radialis tendinitis is a condition characterized by pain over the volar radial wrist caused by inflammation of the FCR tendon sheath.

What nerve Innervates the main elbow flexors?
The muscle is innervated by the musculocutaneous nerve. The lateral portion of the muscle covers the radial nerve as it spirals around the distal humerus.
What does the musculocutaneous nerve innervate?

According to our studies with respect to the flexor pollicis brevis muscle, the superficial head receives innervation of the median nerve and the deep head receives innervation of the median and ulnar nerves (double innervation).
Where is flexor carpi digitorum?
Flexor carpi ulnaris is a fusiform muscle located in the anterior compartment of the forearm. It belongs to the superficial flexors of the forearm, along with pronator teres, palmaris longus, flexor digitorum superficialis and flexor carpi radialis.
