Innervation: Deep peroneal/fibular nerve Muscle Origin Insertion Action Innervation Tibialis anterior Lateral surface of the Medial cuneiform Dorsiflexion Deep peroneal nerve tibia Inversion Extensor digitorum longus Lateral condyle of the Fibres converge into Extension of 4 lateral tibia tendon, which travel to the toes *there is also an extensor digitorum brevis dorsal surface of the foot. Dorsiflexion (lies lateral and deep to tibialis anterior) The tendon the splits into 4. Extensor hallucis longus Medial surface of the Tendon crosses anterior to Extension of great fibular shaft ankle joint and attaches to toe (located deep to both) distal phalnx of great toe Dorsiflexion LATERAL COMPARTMENT OF LEG Action: Eversion Innervation: Superficial peroneal/tibial nerve Origin: lateral surface of fibular shaft
