Fig. 16-5. Horizontal section through the lower end of the tibia and fibula. The tendons of the muscles of the three compartments of the leg (see fig. 16-1) are shown, as are also the neurovascular bundles related to the hallucis and digitorum tendons (deep fibular nerve and anterior tibial artery; posterior tibial artery and tibial nerve). The synovial sheaths (see fig. 17-1) are not represented. The plantaris muscle is seen joining the medial side of the calcaneal tendon. Some important muscular functions are indicated. Dorsiflexion and plantar flexion take place at the ankle joint, whereas inversion and eversion occur at more distal joints. (See fig. 17-7.) (Modified from Castaing and Soutoul.)
