GENERAL HISTOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -A nociceptor ("pain receptor” from Latin nocere ‘to harm or hurt’) is a sensory neuron that responds to damaging or potentially damaging stimuli by sending “possible threat” signals to the spinal cord and the brain.

Detailed explanation-3: -There are two types of nociceptive pain – visceral and somatic. Somatic Pain is pain in your muscles, skin, or bone. This pain is focused on a specific area and could be the type of pain you feel with movement, when experiencing a headache, or when you cut your skin.

Detailed explanation-4: -Radicular pain. Radicular pain occurs when the nerve roots are irritated. Somatic pain. Somatic pain happens when any of the pain receptors in your tissues, such as muscles, bone, or skin, are activated. Visceral pain. 12-Oct-2017
