caption_attribution_description: Lumbricales pedis muscles
context_page_description: The lumbricals are four small skeletal muscles, accessory to the tendons of the flexor digitorum longus and numbered from the medial side of the foot; they arise from these tendons, as far back as their angles of division, each springing from two tendons, except the first.So the first lumbricle is unipenate and second, third and fourth are bipenate.
  The muscles end in tendons, which pass forward on the medial sides of the four lesser toes, and are inserted into the expansions of the tendons of the Extensor digitorum longus on the dorsal surfaces of the proximal phalanges. All four lumbricals insert into extensor hoods of the phalanges, thus creating extension at the inter-phalangeal joints. However, as the tendons also pass inferior to the metatarsal phalangeal joints it creates flexion at this joint.

However, as the tendons also pass inferior to the metatarsal phalangeal (MTP) joints it creates flexion at this joint.
