Sensory receptors

[Tokspor]

Are sensory receptors, like nociceptors for pain, the nerves which transmit information to the CNS, which then processes it and then tells the somatic nervous system what should be done, like initiating a reflex arc? If that is the case, are sensory receptors classified as part of the CNS?

sensory neuron = afferent = goes TO brain/spinal cord.

 

[Charles_Carmichael]

The neurons associated with sense are part of the peripheral nervous system. The CNS includes only the brain and spinal cord (basically, the two things that are enclosed within the meninges). Is this what you were asking?

Reflex arcs will go from the sensory neuron to a interneuron located in the spinal cord then back to the effector muscle. They synapse the interneuron in the cns.

I think one of the questions was missed.
Sensory receptors is a broad term for all receptors that bring information to the CNS. These include osmolar receptors, chemo receptors, stretch receptors, nociceptors, hot receptors, cold receptors, etc. etc. etc.

Receptors are only part of the PNS, which bring information TO the CNS (afferent neurons). Remember, CNS is the BRAIN and the SPINAL CORD only! All other neurons that take information away from the CNS (efferent, such as motor neurons) or bring the information to the CNS (afferent) are part of the PNS. All sensory neurons are afferent and part of the PNS.
