Anterior compartment: comprised of tibialis anterior, extensor digitorum longus, and extensor hallucis longus muscles. Lateral compartment: comprised of peroneus longus and brevis muscles. Deep compartment: comprised of the tibialis posterior, flexor digitorum longus, and flexor hallucis longus muscles.
