Final answer:
The lingual surface of the tooth is closest to the tongue.
The correct answer is B. Tongue.
Step-by-step explanation:
The lingual surface of the tooth is closest to the tongue. The tongue is a fleshy, muscular organ that manipulates food for chewing and swallowing. It is attached to the floor of the mouth and contains taste buds, which sense chemicals in food and send signals to the brain to enable the sense of taste.
The lingual surface of the tooth refers to the surface that is closest to the tongue. In dental and anatomical terms:
- Buccal surface: The surface of a tooth that is closest to the cheek or lips.
- Lingual surface: The surface of a tooth that is closest to the tongue.
- Palatal surface: The surface of an upper tooth that is closest to the palate (roof of the mouth).
So, the lingual surface is associated with the tongue.
The correct answer is B. Tongue.
