About the transverse abdominal of the pig
Transverse abdominal is a muscle of the hips and pelvis (pelvis), one on each side of the body. Its name in the Nomina Anatomica Veterinaria is Musculus transversus abdominis. You can turn it above, see it in place in the hips and pelvis of the pig, 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.
