Sections:
The lumbrical muscles of the foot are four muscles that originate from the tendons of the flexor digitorum longus and pass dorsally to insert into the free medial margins of the extensor hoods of the four lateral toes.
Summary
-
origin
- first lumbrical: medial side of tendon of the flexor digitorum longus associated with the second toe
- second, third and fourth lumbricals: adjacent surfaces of adjacent tendons of flexor digitorum longus.
- insertion: medial free margins of extensor hoods of toes II to V
- action: flexion of metatarsophalangeal joint and extension of interphalangeal joints
- arterial supply: medial and lateral plantar arteries
-
innervation
- first lumbrical: medial plantar nerve from the tibial nerve
- second, third and fourth lumbricals: lateral plantar nerve from the tibial nerve
