After describing the pathophysiology of pain, an instructor determines that the students have understood the teaching when they identify which of the following as being responsible for transmitting the sensations to the central nervous system?
a)transduction
b)modulation
c)nociceptors
d)cytokines

The correct option is: C) Nociceptors

Explanation:

Nociceptors, also known as the pain receptor, is a type of sensory receptor, developed from the neural-crest stem cells that causes the perception of pain and responds to the harmful stimuli by sending signals to the spinal cord and brain.

They are of two types internal and external. Internal nociceptors are found in organs like bladder, guts, digestive tract, joints and muscles. Whereas, the external nociceptors are present on the skin, corneas and mucosa.
