Which structure is NOT a division of the pharynx?

Explanation:
The pharynx is organized into three regions: a section behind the nasal cavity (nasopharynx), a section behind the oral cavity (oropharynx), and a section behind the larynx that leads to the esophagus and larynx (laryngopharynx). The trachea is not part of the pharynx; it’s the windpipe that continues inferiorly from the larynx to the lungs. So the structure that is not a division of the pharynx is the trachea.
