Explanation:

Caudal is an anatomic term used to describe or reference a body part that it's located near the "tail-end of the body". It comes from the Latin "cauda" which means "tail".

In these case the incision is heading from the Cranial or Cephalic direction (head), towards the Caudal-end of the animal (tail).
