About the masseter muscle of the horse
Masseter muscle is a muscle of the head (head), one on each side of the body. Its name in the Nomina Anatomica Veterinaria is Musculus masseter. You can turn it above, see it in place in the head 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.
