Lumbrical Muscles of the Foot – Human Anatomy | Kenhub

Hey there everyone! It’s Matt from Kenhub,
and in this tutorial, we will discuss the lumbrical muscles of the foot. The lumbrical
muscles of the foot are part of the central muscles of the sole of the foot that lie within
the central compartment between the muscles of the big and little toes. The compartment
comprises numerous short foot muscles in different layers. Together, they form the central surface
of the sole of the foot. The other muscles in this group include the flexor digitorum
brevis muscle, the quadratus plantae muscle, the plantar interossei muscles, and the dorsal
interossei muscles. The innervation for the lumbricals muscles
of the foot is provided by two nerves, the medial plantar nerve and the lateral plantar
nerve, shown here in green which are both branches of the tibial nerve. The lumbrical muscles originate at the tendons
of the flexor digitorum longus muscle at the distal end of the quadratus plantae muscle
and insert medially at the proximal phalanges of the second to fifth toes and dorsal aponeurosis. The muscles of the central compartment fulfill
various tasks. The lumbricals along with the plantar interossei muscles allow flexion at
the metatarsophalangeal joint and adduction of the toes. This video is more fun than reading a textbook,
