Flexor Digiti Minimi Brevis action
Flexes little toe at metatarsophalangeal joint
Flexor Digiti Minimi Brevis innervation
Lateral plantar branch of tibial nerve
Flexor Hallucis Brevis origin and insertion
origin: Mostly from cuboid bone; insertion: Via two tendons onto both sides of the base of the proximal phalanx of big toe; each tendon has a sesamoid bone in it
Adductor Hallucis action
Helps maintain the transverse arch of foot; weak adductor of big toe
Adductor Hallucis innervation
Lateral plantar branch of tibial nerve
Lumbricals origin and insertion
origin: From each tendon of flexor digitorum longus; insertion: Extensor expansion on proximal phalanx of toes 2-5, medial side
Flexor Hallucis Brevis action
Flexes big toe’s metatarsophalangeal joint
Flexor Hallucis Brevis innervation
Medial plantar branch of tibial nerve
Flexor Accessorius (Quadratus Plantae) origin and insertion
origin: Medial and lateral sides of calcaneus; insertion: Tendon of flexor digitorum longus in midsole
Lumbricals action
By pulling on extensor expansion, flex toes at metatarsophalangeal joints and extend toes at interphalangeal joints
Lumbricals innervation
Medial plantar nerve (first lumbrical); Lateral plantar nerve (second to fourth lumbricals)
Abductor Digiti Minimi origin and insertion
origin: Tuber calcanei; insertion: Lateral side of base of little toe’s proximal phalanx
Flexor Accessorius (Quadratus Plantae) action
Straightens out the oblique pull of flexor digitorum longus
Flexor Accessorius (Quadratus Plantae) innervation
Lateral plantar branch of tibial nerve
Abductor Hallucis origin and insertion
origin: Tuber calcanei and flexor retinaculum; insertion: Proximal phalanx of big toe, medial side, via sesamoid bone in the tendon of flexor hallucis brevis
Abductor Digiti Minimi action
Abducts little toe
Abductor Digiti Minimi innervation
Lateral plantar branch of tibial nerve
Flexor Digitorum Brevis origin and insertion
origin: Tuber calcanei; insertion: Middle phalanx of toes 2-4
Abductor Hallucis action
Abducts big toe
Abductor Hallucis innervation
Medial plantar branch of tibial nerve
Extensor Digitorum Brevis origin and insertion
origin: Anterior part of calcaneus bone; extensor retinaculum; insertion: Base of proximal phalanx of big toe; extensor expansions on toes 2-4
Flexor Digitorum Brevis action
Helps flex toes
Flexor Digitorum Brevis innervation
Medial plantar branch of tibial nerve
Tibialis Posterior origin and insertion
origin: Extensive origin from superior tibia and fibula and interosseous membrane; insertion: Tendon passes behind medial malleolus and under arch of foot; inserts into several tarsals and metatarsals 2-4
Extensor Digitorum Brevis action
Helps extend toes at metatarsophalangeal joints
