Dorsal interossei- Abduction of toes 2 to 4
- Flexion of interphalangeal joints
- Sides of adjacent metatarsals- Dorsal bases of proximal phalanges of toes 2-4- Lateral plantar nerve from tibial nerve : S2,3- Dorsalis metatarsal 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
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
