Q. 10 - Biology

Question

Many diabetic patients are warned by their doctors to test their glucose levels by pricking the sides of their fingers rather than the pads. Pricking the sides avoids stimulating which receptor? a. Krause end bulbs b. Meissner’s corpuscles c. Ruffini ending d. Nociceptors

Step-by-Step Solution

Answer

Option b is correct.

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 b is correct because Messiner's corpuscles also known as tactile corpuscles are found in the upper epidermis and do not extend to the lower epidermis. 

Step 3. Explanation of the incorrect option

Option a is incorrect because Krause end bulbs are cutaneous receptors in the human body.

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

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

Option di is incorrect because the nociceptor detects signals from damaged tissue.
