Neuromuscular, Digestive and Respiratory Systems: Nociceptors

Nociceptors

NOCIOCEPTORS

Nocioceptors

These detect pain sensation by naked nerve endings. This sensation does not have any special structure to mediate. These nociceptors are available in the superficial layers of dermis, which are represented by non-medullated fibers. They act as protective response to an injurious stimulus.

Vibratory sense

It is mediated by tactile and pressure receptors namely Merkel’s discs and Pacinian corpuscles.

Itching and tickling sense

It is mediated by stimulation of both tactile and pain receptors.
