Nerves and blood vessels to upper part of tibialis anterior muscle
The tibialis anterior has been detached from its origins on the tibia and interosseous membrane. The muscle has been retracted laterally. Branches of the deep peroneal nerve (10, 12) enter the anterior muscular compartment by passing through the anterior intermuscular septum (8). The upper one of these branches supplies periosteum as well as muscle, whereas the lower branch passes directly into the muscle. The recurrent branch of the anterior tibial artery (11), with its accompanying veins, sends branches into the muscle.
