Mouth Pain Anatomy
To better understand mouth or tongue pain, it helps to understand the anatomy of the mouth and throat.
The back of throat is also referred to as the pharynx. More specifically, the pharynx is the back, upper part of the throat behind the tongue. It starts at the base of the tongue and ends at the larynx.
The tonsils are collections of lymphoid tissue in the back of the throat. They are located on both sides of the throat, near the base of the tongue. The tonsils generally shrink over time. At puberty, the tonsils are normally about the size of an almond.
