Multiple Choice
Which of the following receptors is stimulated by a substance known as capsaicin?
A
tactile (Meissner's) corpuscles
B
vanilloid receptors
C
Golgi tendon organs
D
lamellar (Pacinian) corpuscles
Verified step by step guidance
1
Understand the role of capsaicin: Capsaicin is a compound found in chili peppers that is known to cause a sensation of heat or burning when it comes into contact with tissues.
Identify the type of receptor that responds to capsaicin: Capsaicin specifically activates a type of receptor known as the vanilloid receptor, also referred to as the TRPV1 receptor.
Differentiate between the receptors listed: Tactile (Meissner's) corpuscles are responsible for detecting light touch, Golgi tendon organs are involved in sensing changes in muscle tension, and lamellar (Pacinian) corpuscles detect deep pressure and vibration.
Recognize that vanilloid receptors are not involved in touch, pressure, or muscle tension, but rather in detecting temperature and pain, particularly the sensation of heat caused by capsaicin.
Conclude that the vanilloid receptors are the correct receptors stimulated by capsaicin, as they are specifically sensitive to this compound and are involved in the sensation of heat and pain.
