The '''anterior interosseous nerve''' ('''volar interosseous nerve''') is a branch of the [[median nerve]] that supplies the deep muscles on the front of the [[forearm]], except the ulnar half of the [[flexor digitorum profundus]]. 

It accompanies the [[anterior interosseous artery]] along the front of the [[interosseous membrane of the forearm]], in the interval between the [[flexor pollicis longus]] and [[flexor digitorum profundus]], supplying the whole of the former and the radial half of the latter, and ending below in the [[pronator quadratus]] and [[wrist joint]].

Many texts, for simplicity's sake, consider this nerve part of the [[median nerve]]. 
 
==Innervation==
The anterior interosseous nerve innervates 2.5 muscles:
* [[flexor pollicis longus]]
* [[pronator quadratus]]
* the radial (lateral) half of [[flexor digitorum profundus]]

These muscles are in the deep level of the [[anterior compartment of the forearm]].
