The lumbrical muscles of the foot are part of the central muscles of the sole of the foot. The central muscles of the sole of the foot include the lumbricals, flexor digitorum brevis, quadratus plantae, plantar and dorsal interossei muscles.

The lumbrical muscles originate at the tendons of the flexor digitorum longus muscle and have their insertion on the proximal phalanges of the second to fifth toes and the dorsal aponeurosis.

The lumbricals are innervated by the medial and lateral plantar nerves, both branches of the tibial nerve.

They perform flexion at the metatarsophalangeal joint and adduct the toes.

In this video tutorial we will take a look at these muscle facts about the lumbrical muscles: origin, insertion, innervation and function:

- 0:10 central foot sole muscles
- 0:46 lumbricals innervation
- 1:02 lumbrical muscles origin and insertion
- 1:22 lumbricals of the foot function
