Question

Identify the papillae of the tongue shown in the image below:

• A. Circumvallate
• B. Fungiform
• C. Filiform
• D. Foliate

Answer 1

The Correct Option is A

The papillae of the tongue in question are the circumvallate papillae. These are large, dome-shaped structures situated at the posterior third of the tongue. They are arranged in a V-shape, typically numbering 8 to 12, located just in front of the sulcus terminalis. Here is how they differ from other types of papillae:

Type	Description
Circumvallate	Large, dome-shaped, located at the back of the tongue in a V-formation, contain taste buds.
Fungiform	Mushroom-shaped, found mostly at the tip and sides of the tongue, contain taste buds.
Filiform	Thread-like, covering most of the tongue's surface, do not contain taste buds.
Foliate	Leaf-like structures on the sides at the back of the tongue, contain taste buds.

The distinguishing features of circumvallate papillae, such as their placement and shape, were key identifiers in correctly identifying them in the image provided.
