Verified step by step guidance

Step 1: Begin by understanding the anatomical location of the palatine tonsils. These are part of the lymphatic system and play a role in immune defense by trapping pathogens entering through the mouth or nose.

Step 2: Recall the divisions of the pharynx: nasopharynx (upper part, behind the nasal cavity), oropharynx (middle part, behind the oral cavity), and laryngopharynx (lower part, leading to the larynx and esophagus). Each has distinct anatomical features and functions.

Step 3: Focus on the oropharynx, which is located posterior to the oral cavity and extends from the soft palate to the upper border of the epiglottis. This region contains the palatine tonsils, which are situated in the lateral walls of the oropharynx.

Step 4: Eliminate the incorrect options: The nasopharynx is above the soft palate and does not contain the palatine tonsils. The laryngopharynx is below the oropharynx and leads to the esophagus and larynx, also not housing the palatine tonsils. The oral cavity proper refers to the space within the teeth and gums, which is not where the palatine tonsils are located.

Step 5: Conclude that the palatine tonsils are located in the lateral walls of the oropharynx, based on their anatomical position and function.
