Taste buds are located primarily on which anatomical structure?

Taste buds are located primarily on which anatomical structure?

• A. The tongue, covered by papillae
• B. The nasal cavity
• C. The retina
• D. The cochlea

Answer: (A)

Taste buds are the sensory organs for gustation and are housed primarily in the tongue’s surface within structures called papillae. The tongue has many papillae—fungiform toward the front, circumvallate at the back, and foliate along the sides—each containing taste buds with gustatory receptor cells that extend microvilli into a taste pore to detect tastants. This high concentration on the tongue makes it the main site for tasting. The other structures listed serve different senses: the nasal cavity for smell, the retina for vision, and the cochlea for hearing, so they do not contain taste buds.
