What does 'dorsum of the tongue' refer to?

  1. The underside of the tongue

  2. The tip of the tongue

  3. The top surface of the tongue

  4. The side surfaces of the tongue

The correct answer is: The top surface of the tongue

The term 'dorsum of the tongue' refers specifically to the top surface of the tongue. In anatomical terminology, "dorsum" generally denotes the upper or back part of an organ. The dorsum of the tongue is the area that is visible when someone opens their mouth and sticks out their tongue. It is covered with mucous membrane and contains the taste buds located within the small papillae, which play a crucial role in the sense of taste. Understanding the anatomical structures of the tongue, including the dorsum, is essential for dental professionals in diagnosing and treating various conditions related to the oral cavity.
