Q. 9 - Biology

Question

If you were to burn your epidermis, what receptor type would you most likely burn? a. free nerve endings b. Ruffini endings c. Pacinian corpuscle d. hair receptors

Step-by-Step Solution

Answer

The correct option is a.

Step 1. Introduction

Sensory receptors are located in sense organs such as skin, nose, eyes, ear, and tongue which detect and respond to external stimuli.

Step 2. Explanation of the correct option

The correct option is a because free nerve endings are the encapsulated dendrites of sensory nerves which sense burns.

Step 3. Explanation of the incorrect option

Option b is incorrect because Raffini endings are present on glabrous and hairy skin and these are encapsulated mechanoreceptors.  

Option c is incorrect because Pacini corpuscles are situated in the dermis of glabrous and hairy skin.

Option di is incorrect because Hair receptors are found in cochlea.
