Question
Chapter 9.2, Problem 8QC
Summary Introduction
To review:
The functioning of the pharyngeal constrictor muscles in the process of swallowing.
Introduction:
There are two steps of muscular action that takes place during the swallowing process. The first step pushes the food toward the end of the oral cavity, while the second step aids in swallowing down of the food through the passageway (esophagus), which, in turn, connects the pharynx to the stomach.
