Final answer:
Peristaltic waves do not occur in the pharynx; they typically take place in the esophagus, stomach, and intestines during the process of digestion.
Step-by-step explanation:
The student asked whether peristaltic waves occur in the pharynx, with the answer being false. Peristalsis refers to the process of muscle contractions and relaxations that move food through the digestive tract. While the pharynx is involved in the swallowing process, peristaltic waves as defined typically occur in the esophagus, stomach, and intestines, not the pharynx.
