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.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.
