Multiple Choice
Which of these is a deep pressure receptor?
A
Merkel's disc
B
Pacinian corpuscle
C
Ruffini ending
D
Meissner's corpuscle
Verified step by step guidance
1
Begin by understanding the function of each receptor listed. Each receptor is responsible for detecting different types of stimuli on the skin.
Merkel's disc is known for detecting light touch and texture. It is not involved in sensing deep pressure.
Ruffini endings are responsible for detecting skin stretch and sustained pressure, but they are not primarily known for deep pressure.
Meissner's corpuscles are sensitive to light touch and vibrations, typically found in areas like fingertips. They do not detect deep pressure.
Pacinian corpuscles are specialized for detecting deep pressure and vibration. They are located deeper in the dermis and subcutaneous tissue, making them the correct answer for deep pressure detection.
