Fig. 16-1. Horizontal section through the middle of the leg. In A, the nerves and vessels are identified. B shows the extensors (supplied by the deep fibular nerve) anteriorly, the fibular muscles (supplied by the superficial fibular nerve) laterally, and the flexors (supplied by the tibial nerve) posteriorly. The posterior compartment contains superficial and deep muscles, separated by the deep transverse fascia of the leg. E.D.L., extensor digitorum longus; E.H.L., extensor hallucis longus; F.D.L., flexor digitorum longus; F.H.L., flexor hallucis longus; F.L., fibularis longus; T.A., tibialis anterior; T.P., tibialis posterior.
