About the descending pectoral muscle of the cat
Descending pectoral muscle is a muscle of the front leg (thoracic limb), one on each side of the body. Its name in the Nomina Anatomica Veterinaria is Musculus pectoralis descendens. You can turn it above, see it in place in the front leg of the cat, 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.
