Insertion: Hallux
Action: Abducts the hallux
4. Medial plantar nerve

Front 22

Special fact about digit 2

Back 22

It abducts either way, but does nott adduct

Front 25

3rd layer of foot muscles

Back 25

don't have to know!

Front 26

Flexor Hallucis Longus

Back 26

Position: Most lateral muscle on posterior leg, yet crosses to wrap around medial malleolus to hallux.
Action: plantarflexion, hallux flexion
Nerve: Tibial
