Whenever our body is under the pathological phenomenon of some disease or has been injured, chemicals are released at that site. These chemicals sensitize the area and stimuli are detected in the form of pain. After the reception of the stimulus, signals are generated that are transmitted with the help of the neurons to the higher brain centers.

These signals activate particular brain areas and as a result of sensitization of the brain, neurotransmitters are released that convey the responsive signal to the effector organ. After that, a response is generated in the body. This is the actual response to the pain. Different people respond in a different ways to different painful stimuli.

These responses are classified into

  • Motor response
  • Cognitive response
  • Behavioral response

Motor response

Behavioral response

It consists of changes in the body movements, that are to be maintained to avoid pain from increasing. For example, in case of a fracture of the hand or foot, the person stops mobilizing his/her foot to minimize the chances of dislocation until his / her fractured bones are healed properly.

Cognitive response

It can also be termed as an emotional response that how a person takes this painful stimulus. Some people start crying, some get angry or agitated, and some get tensed and depressed.

All these changes are also stored in the brain in the form of memory so that whenever the person feels the same stimulus of pain again he recalls all the events and responds accordingly. Some people get anxious and worried. This also helps the person to immediately take his medicine to control pain at its initial stages.
