You learned in your psychology course that nociceptors, which are found in the skin, muscles, and internal organs, are specialized sensory receptors for pain. when you left class, a friend asked you about the difference between proprioceptors and nociceptors. you explained that proprioceptors are to as nociceptors are to

The proprioceptors are the sensors in the limbs, which give information regarding the muscle length, joint angle, and muscle tension that is combined to provide knowledge regarding the alignment of the limb in space. The muscle spindle is one of the kinds of proprioceptor, which gives information regarding the changes in the length of the muscle.  

On the other hand, a nociceptor refers to a sensory neuron, which reacts towards the potentially damaging or destructing stimuli by conducting probable danger signals towards the brain and the spinal cord.  

Proprioceptors are to reflex actions as nociceptors are to pain perception.
