Detailed explanation-1: -Pain is output from the brain. The brain uses a virtual “road map” to direct an output of pain to tissues that it suspects may be in danger. This process is a means of communication between the brain and the tissues of the body, and serves as a defense against possible injury or disease.
Detailed explanation-2: -When we feel pain, such as when we touch a hot stove, sensory receptors in our skin send a message via nerve fibres (A-delta fibres and C fibres) to the spinal cord and brainstem and then onto the brain where the sensation of pain is registered, the information is processed and the pain is perceived.
Detailed explanation-3: -Pain triggers a variety of reactions in our bodies too. Our blood pressure rises, our breathing quickens and stress hormones are released. The body quickly notices that something is not right, that it’s ill or injured and needs to visit a doctor or hospital.
Detailed explanation-4: -(A) Nociceptive pain represents the sensation associated with the detection of potentially tissue-damaging noxious stimuli and is protective.
