| Muscle | Origin | Insertion | Action | Nerve |
| Anterior Compartment: |
| tibialis anterior | anterior proximal tibia (lateral tibial condyle, proximal 2/3 of anterolateral surface of tibia & interosseous membrane) | medial cuneiform & base of 1st metatarsal (medial & plantar surfaces) | dorsiflexion of foot at ankle; inverts of foot (at tarsal joints) | deep peroneal (fibular) nerve (L4, L5, S1) |
| extensor digitorum longus | proximal 2/3 of fibula, interosseous membrane, lateral condyle of tibia (anterior surfaces) | dorsal surface of toes #2-5 (via dorsal expansion to middle & distal phalanges) | extension of toes #2-5 (at MTP & IP joints); dorsiflexion & eversion of foot | deep peroneal (fibular) nerve (L4, L5, S1) |
| extensor hallucis longus | anterior middle 1/3 of fibula & interosseous membrane | dorsal surface big toe (base of distal phalanx) | extension of big toe at MTP; dorsiflexion & inversion of foot | deep peroneal (fibular) nerve (L4, L5, S1) |
| fibularis (peroneus) tertius | distal 1/3 of anterior fibula (distal & lateral aspect of extensor digitorum longus) | base of 5th metatarsal (dorsal surface) | dorsiflexion & eversion of foot | deep peroneal (fibular) nerve (L5, S1) |
| Lateral Compartment: |
| fibularis (peroneus) longus | head & proximal lateral shaft of fibula | medial cuneiform & base of 1st metatarsal (plantar surfaces) | eversion of foot; plantar flexion of foot | superficial peroneal (fibular) nerve (L5, S1) |
| fibularis (peroneus) brevis | distal lateral 1/2 of fibula | base of 5th metatarsal (lateral aspect) | eversion of foot; plantar flexion of foot | superficial peroneal (fibular) nerve (L5, S1) |
