Question

Receptors of pressure present in deep layers of skin are

• A. Krause's end bulb
• B. Meissner's corpuscles
• C. Corpuscles of Ruffini
• D. Pacinian corpuscles

Answer 1

The correct option is D Pacinian corpuscles

Meissner corpuscles are one of the three types of cutaneous receptors which are sensitive to fine touch. Three types are cutaneous receptors are sensitive to pressure which are namely Pacinian corpuscles, Ruffini endings and Krause end bulbs. Out of these, onion-shaped Pacinian corpuscles lie deep inside the dermis. The Ruffini endings are present deeper in epidermis near the base while the Krause end bulbs are present in specialized regions only, for example, conjunctiva of eyes, mucous membrane of lips and tongue etc. Thus, the correct answer is option D.
