Document Summary

Gastrocnemius & plantaris: gastrocnemius (yellow, plantaris (blue) Gastrocnemius (front & back: origin: just above lateral & medial femoral condyles, insertion: calcaneus via achilles tendon, function: knee flexion, ankle plantar flexion. Plantaris: origin: just above lateral condyle of femur, insertion: calcaneus via achilles tendon, function: knee flexion , ankle plantar flexion. Soleus: origin: head of fibula, medial border of tibia, insertion: calcaneus via achilles tendon, function: ankle plantar flexion. Lateral lower leg musculature: tibialis anterior (blue, extensor digitorum longus (yellow, peroneus longus (green, peroneus brevis (red) Tibialis anterior (lateral view: origin: lateral condyle , anterior upper shaft of tibia, insertion: base of 1st metatarsal, medial cuneiform, function: ankle dorsi flexion & inversion. Dorsal surface of 1st metatarsal & medial suneiform. Middle & distal phalanges of lateral 4 digits. Tibialis posterior & flexor digitorum longus: flexor digitorum longus (yellow, tibialis posterior (blue) Broad attachment on plantar surface of foot. Posterior & inferior surface of fibula: origin, insertion, function.
