Which term describes toward the bottom or tail in the PNS context?

Explanation:
Direction in neuroanatomy uses posterior to mean toward the back of the body. When describing the peripheral nervous system, moving toward the tail end is aligned with the posterior (back) side of the body, so that term best captures “toward the bottom or tail.” In contrast, anterior means toward the front/belly, medial toward the midline, and lateral away from the midline. For example, a pathway that runs toward the back end of the body is described as progressing posteriorly.
