About the thoracic part of the trapezius of the dog

Thoracic part of the trapezius is a muscle of the spine (vertebral column), one on each side of the body. Its name in the Nomina Anatomica Veterinaria is Musculus trapezius pars thoracica. Separated from the cervical part by an aponeurosis over the spine. You can turn it above, see it in place in the spine of the dog, and open it inside the whole animal in Vetomica.

Where it runs from and to
