About the long digital extensor muscle of the horse
Long digital extensor muscle is a muscle of the back leg (pelvic limb), one on each side of the body. Its name in the Nomina Anatomica Veterinaria is Musculus extensor digitorum longus. You can turn it above, see it in place in the back leg of the horse, and open it inside the whole animal in Vetomica.
