The lateral chamber of the foot if formed by the plantar fascia and contains three muscles. Their muscle bellies form the surface of the lateral foot sole (ball of the little toe).

They are all innervated by the lateral plantar nerve (S1-S2), a branch of the tibial nerve. The following muscles lie within the lateral chamber:

- Abductor digiti minimi muscle: This muscle originates at the calcaneal tuberosity and plantar aponeurosis and inserts at the bases proximal phalanx and metatarsal bone of the little toe.

- Flexor digiti minimi brevis muscle: The FDM runs from the metatarsal bone of the little toe and long plantar ligament to the base of the proximal phalanx of the little toe.

- Opponens digiti minimi muscle: The opponens digiti minimi originates at the long plantar ligament, the base of the fifth metatarsal bone and the tendon sheath of the fibularis longus muscle. Thereupon it inserts again at the lateral border of the fifth metatarsal bone. This muscle is not found in all human bodies.
