Question

Which of the following has the fewest taste receptors? a. fungiform papillae b. circumvallate papillae c. foliate papillae d. filiform papillae

Short answer

Option d is correct.

Step-by-step solution

Step 1. Introduction

Receptors are the biological transducer that converts energy from the external and internal environment into an electrical impulse.

Step 2. Explanation of the correct option

Option d is correct because filiform papillae do not have any taste cells hence they contain very few receptors.

Step 3. Explanation of the incorrect option

Option a is incorrect because fungiform papillae have one to eight taste buds that have receptors for pressure and temperature.

Option a is incorrect because circumvallate papillae have approximately 250 taste buds hence they contain a high number of receptors.

Option a is incorrect because foliate papillae contain approximately 1300 taste buds.
