Abductor hallucis- Abducts great toe at MTP joint
- Flexes great toe at MTP joint
(MTP = metatarsophalangeal)
- Medial process calcaneal tuberosity- Medial plantar portion of proximal phalanx of great toe- Medial plantar nerve from tibial nerve: S2, S3- Medial plantar artery
Flexor digitorum brevis- Flexes lateral four toes at proximal interphalangeal joint- Medial process calcaneal tuberosity
- Plantar aponeurosis
- Plantar sides of middle phalanges of lateral four toes- Medial plantar nerve from tibial nerve: S2, S3- Medial plantar artery
Abductor digiti minimi- Abducts little toe at the metatarsophalangeal joint- Lateral and medial processes calcaneal tuberosity
- Lateral base of proximal phalanx of little toe- Lateral plantar nerve from tibial nerve: S2, S3- Lateral plantar artery
