In the forearm, the median nerve directly innervates muscles in the superficial and intermediate layers: - Superficial layer: Pronator teres, flexor carpi radialis and palmaris longus.
- Intermediate layer: Flexor digitorum superficialis.
.
Considering this, what does the median nerve innervate?
Anterior compartment of the forearm Thenar eminence Lumbricals of the hand
Additionally, what happens if median nerve is damaged? The median nerve controls the majority of the muscles in the forearm. If the median nerve is damaged, the ability to abduct and oppose the thumb may be lost due to paralysis of the thenar muscles. Various other symptoms can occur which may be repaired through surgery and tendon transfers.
Regarding this, which of the following muscles is not innervated by the median nerve?
Those muscles in the superficial and deep groups that are not innervated by the median (i.e., the flexor carpi ulnaris and the ulnar part of the flexor digitorum profundus) are supplied by the ulnar nerve. The tendons of the flexor carpi radialis, palmaris longus, and flexor carpi ulnaris are readily palpable.
