Muscle Chart

Popliteus

O: Lateral femoral condyle (above fibular head)

I: posterior surface proximal tibia

N: Tibial nerve

A: stabilize knee joint, unlock knee joint

T: knee bent, go at it at the insertion point (medial tibial)

C: stay away from the midline to avoid tibial nerve

Tibialis Posterior

O: Posterior surfaces of the tibia and fibula (between)

I: wraps around medial malleolus, inserts onto tuberosity and adjacent region of medial cuneiform

N: tibial nerve

A: INV and PF, support medial arch

T: go medially into tibia just distal to the popliteus, redirect and slide the needle under the tibia

Extensor Hallicis Longus

O: middle of medial surface of fibula

I: dorsal base of distal phalanx of great toe

N: Deep fibular

A: ext great toe, DF

Flexor Digitorum Longus

O: Medial posterior surface of tibia

I: plantar surface of distal phalanges of toes 2-5

N: tibial nerve

A: flex toes 2-5

C: tibial nerve and artery live centrally and at the distal 3rd of the lower leg will move towards the medial malleolus

Flexor Hallucis Longus

O: Posterior surface of fibula

I: plantar surface of distal phalanx of great toe

N: tibial nerve

A: flex great toe
