Muscles of the forearm – anterior group

8.3.1

The anterior muscles of the forearm are divided into four layers. They are flexors and pronators of the forearm. These 

muscles are innervated predominantly by the median nerve, although  the flexor carpi ulnaris  and part of the flexor 

digitorum profundus are innervated by the ulnar nerve. The pronator teres, flexor carpi ulnaris and flexor digitorum 

superficialis each have two heads, through which nerves from the upper arm pass to the forearm. 

Palmaris longus (musculus palmaris longus)
