About the iliacus of the horse
Iliacus 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 iliacus. 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.
Where it runs from and to
A muscle is told apart from its neighbours by what it takes hold of at each end, which is also what decides what it does when it shortens.
