Verified step by step guidance

Step 1: Understand the anatomical regions of the tongue. The tongue is divided into two main parts: the anterior two-thirds (oral part) and the posterior one-third (pharyngeal part). These divisions are based on their location and function.

Step 2: Learn the terminology associated with the tongue. The 'oral part' refers to the anterior two-thirds of the tongue, which is involved in speech and manipulation of food. The 'pharyngeal part' refers to the posterior one-third, which is involved in swallowing and connects to the pharynx.

Step 3: Clarify the other options provided. The 'palatine portion' is not a standard anatomical term for the tongue but may refer to structures near the palate. The 'lingual frenulum' is a fold of mucous membrane that anchors the tongue to the floor of the mouth and is not related to the posterior third of the tongue.

Step 4: Recognize that the posterior third of the tongue is anatomically and functionally distinct. It contains lymphatic tissue (lingual tonsils) and is part of the oropharynx, making 'pharyngeal part' the correct term.

Step 5: Conclude that the correct anatomical term for the posterior third of the tongue is the 'pharyngeal part,' as it is the region connected to the pharynx and involved in swallowing.
