Verified step by step guidance

Understand the anatomical regions of the pharynx: The pharynx is divided into three parts—nasopharynx, oropharynx, and laryngopharynx. Each region has distinct boundaries and functions.

Identify the nasopharynx: The nasopharynx is located posterior to the nasal cavity and above the soft palate. It primarily serves as an air passageway.

Identify the oropharynx: The oropharynx lies posterior to the oral cavity and extends from the soft palate to the upper border of the epiglottis. It serves as a passageway for both air and food.

Determine the transition point: The transition from the nasopharynx to the oropharynx occurs at the level of the soft palate, which acts as a boundary between these two regions.

Review anatomical landmarks: The hyoid bone, thyroid cartilage, and epiglottis are located lower in the neck and are associated with the laryngopharynx or other structures, not the transition between the nasopharynx and oropharynx.
