Medial head of flexor hallucis brevis at a glance
- What it is
- The medial part of flexor hallucis brevis in the sole.
- Location
- Origin: flexor hallucis brevis as a whole arises from the plantar surfaces of the cuboid and lateral cuneiform and the tibialis posterior tendon. Insertion: medial side of the base of the proximal phalanx of the great toe, with abductor hallucis, through the medial sesamoid bone.
- Function
- Flexes the great toe at the metatarsophalangeal joint.
- Body system
- Muscular · paired (left and right)
- FMA ID

Key facts
- Innervation: medial plantar nerve (S2–S3)
- The tendon of flexor hallucis longus runs between the two heads and their sesamoids, which protect it.
- Lies in the third layer of the sole.
