Dorsal interossei of the foot
In human anatomy, the dorsal interossei of the foot are four muscles situated between the metatarsal bones.Although small, the dorsal interossei are powerful muscles that, together with their plantar counterparts, control the direction of the toes during violent activity, thus allowing the long and short flexors to perform their actions.[1] The first and second dorsal interossei muscles additionally receive innervation from the lateral branch of the deep fibular nerve.[4] In the angular interval left between the heads of each of the three lateral muscles, one of the perforating arteries passes to the dorsum of the foot; through the space between the heads of the first muscle the deep plantar branch of the dorsalis pedis artery enters the sole of the foot.[3] This article incorporates text in the public domain from page 495 of the 20th edition of Gray's Anatomy (1918)
