Peroneus Tertius - Insertion dorsal surface of bone & proximal shaft of 5th metatarsal in front of malleolus
Peroneus Tertius - Action dorsiflex, eversion, opposes tibialis anterior
Peroneus Longus - Origin head of fibula, , upper 2/3 of lateral surface of fibula
Peroneus Longus - Insertion lateral side of inferior surface of medial cuneiform & base of 1st metatarsal
Peroneus Longus - Action plantar flexion and eversion of the foot
Peroneus Brevis - Origin inferior 2/3 of lateral fibula passes behind lateral malleolus & passes superior to the peroneal tubercle
Peroneus Brevis - Insertion tuberosity of the base of 5th metatarsal
Peroneus Brevis - Action Eversion of the foot, plantarflex
Gastrocnemius - Origin Lateral Head - Lateral epicoondyle of femur Medial Head - posterior femur proximal to medial epicondyle(back and above)
Gastrocnemius - Insertion Calcaneus via achilles/calcaneal tendon
Gastrocnemius - Action Flexes knee & plantarflexes ankle
Soleus - Origin posterior fibula - head and upper 1/4 tibia - soleal line & medial border
Soleus - Insertion Calcaneus via achilles/calcaneal tendon
Soleus - Action plantarflexes ankle, postural muscle

Tibialis Posterior - Action inversion, plantar flexion, maintains arches
Extensor Digitorum Brevis - Origin anterior dorsal surface of calcaneus & inferior extensor retinaculum
Extensor Digitorum Brevis - Insertion proximal phalanx of big toe, blends w tendons of Extensor Digitorum Longus to toes #2-4
Extensor Digitorum Brevis - Action extends toes #1-4, big toe part can be called extensor hallucis brevis
Abductor Hallucis - Origin medial part of calcaneus, plantar aponeurosis, flexor retinaculum
Abductor Hallucis - Insertion medial side of base of proximal phalanx of big toe
Abductor Hallucis - Action abducts and flexes big toe, supports medial longitudinal arch of the foot
Flexor Digitorum Brevis - Origin inferior surface of tubercalcanei, plantar aponeurosis, divides into 4 tendons
Flexor Digitorum Brevis - Insertion middle phalanges of toes 2-5 both medial and lateral sides (superficial to tendon of flexor digitorum longus)
