nociceptors are responsible for the perception of?
328821
Specialized peripheral sensory neurons known as nociceptors alert us to potentially damaging stimuli at the skin by detecting extremes in temperature and pressure and injury-related chemicals, and transducing these stimuli into long-ranging electrical signals that are relayed to higher brain centers.

Mechanoreceptors are sensory neurons or peripheral afferents located within joint capsular tissues, ligaments, tendons, muscle, and skin.

Olfactory receptors are examples of a pain receptors.

Peripheral sensitization is due to posttranslational and transcription changes in the terminal ends of high-threshold nociceptors resulting in primary hyperalgesia. Central sensitization in contrast typically manifests in tactile allodynia and secondary hyperalgesia (in tissue not affected by any harmful condition).

Sensory. The sensory function of the nervous system involves collecting information from sensory receptors that monitor the body's internal and external conditions. These signals are then passed on to the central nervous system (CNS) for further processing by afferent neurons (and nerves).

Key Points The neurons (or excitable nerve cells) of the nervous system conduct electrical impulses, or signals, that serve as communication between sensory receptors, muscles and glands, and the brain and spinal cord.

Sensation refers to the process of sensing our environment through touch, taste, sight, sound, and smell. This information is sent to our brains in raw form where perception comes into play. Perception is the way we interpret these sensations and therefore make sense of everything around us.

Nociceptors are specialized nerve endings for detection of potential tissue harm by mechanical, thermal or chemical stimuli. Where are cell bodies of nociceptors found? Outside of the CNS in dorsal horn ganglia.

The sensory (also known as afferent) division of the nervous system contains nerves that come from the viscera (internal organs) and the somatic areas (muscles, tendons, ligaments, ears, eyes and skin). These nerves conduct impulses to the PNS/CNS providing information on what is happening within and outside the body.

Cutaneous receptor. The cutaneous receptors' are the types of sensory receptor found in the dermis or epidermis. They are a part of the somatosensory system. Cutaneous receptors include cutaneous mechanoreceptors, nociceptors (pain) and thermoreceptors (temperature).

This system is responsible for all the sensations we feel – cold, hot, smooth, rough, pressure, tickle, itch, pain, vibrations, and more. Within the somatosensory system, there are four main types of receptors: mechanoreceptors, thermoreceptors, pain receptors, and proprioceptors.

Sensation is input about the physical world obtained by our sensory receptors, and perception is the process by which the brain selects, organizes, and interprets these sensations. In other words, senses are the physiological basis of perception.

Sensory neurons send impulses from sensory receptors to inform the CNS of a stimulus. ... Sensory neurons have long dendrites and short axons. The dendrites of a sensory neuron are found outside the spinal cord in the skin, muscle or gland of their particular sensory receptor.

That is, they see, hear, smell, taste, and feel. Many of our pains arise from pressure, shock, heat and other stimuli administered at high levels—and insects most assuredly respond to these bodily sensations. Insects can even detect stimuli that are outside of our sensory scope.
