MUSCLE RECEPTORS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Someone lightly taps you on your shoulder, making you look back. Which specific receptors were stimulated by the tap on your shoulder?
A
Meissner’s Corpuscles
B
Ruffini’s Corpuscles
C
Free Nerve Endings
D
Merkel’s Discs
Explanation: 

Detailed explanation-1: -Meissner corpuscles are considered low-threshold phasic receptors in that they adapt quickly to a stimulus. With sustained stimulation, the response of Meissner corpuscles decreases rapidly before ceasing. Such receptors are unable to convey information regarding the duration of the stimulus.

Detailed explanation-2: -Cutaneous receptors Merkel discs and Meissner corpuscles are located near the surface of the skin at the dermal–epidermal junction, are highly sensitive to localized vertical pressure, and contribute to the sense of light touch.

Detailed explanation-3: -Meissner’s corpuscles respond to touch and low-frequency vibration. Ruffini endings detect stretch, deformation within joints, and warmth.

Detailed explanation-4: -Merkel’s disks, which are unencapsulated, respond to light touch. Meissner’s corpuscles, Ruffini endings, Pacinian corpuscles, and Krause end bulbs are all encapsulated. Meissner’s corpuscles respond to touch and low-frequency vibration. Ruffini endings detect stretch, deformation within joints, and warmth.
