Question: How does the nervous system react to pain?

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.

How does pain affect the nervous system?

Chronic pain can make the nervous system more sensitive to pain. For example, chronic pain repeatedly stimulates the nerve fibers and cells that detect, send, and receive pain signals. Repeated stimulation can change the structure of nerve fibers and cells (called remodeling) or make them more active.

How does the body respond to pain?

Transduction. During transduction, the pain stimulus is transformed into a nerve impulse. Receptors on the surface of the nerve endings, called nociceptors, respond to noxious stimuli, which can be thermal (temperature above 40°C), mechanical (extreme pressure over a small area) or chemical (strong acid or alkali).

How the nervous system detects and interprets pain?

Some nerves send signals associated with light touch, while others respond to deep pressure. Special pain receptors called nociceptors activate whenever there has been an injury, or even a potential injury, such as breaking the skin or causing a large indentation.

How do I know if my nervous system is damaged?

Signs and symptoms of nervous system disorders

Which spinal nerves affect which parts of the body?

The nerves of the cervical spine go to the upper chest and arms. The nerves in your thoracic spine go to your chest and abdomen. The nerves of the lumbar spine then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles.

Is pain a chemical reaction?

Some chemicals govern mild pain sensations; others control intense or severe pain. The body’s chemicals act in the transmission of pain messages by stimulating neurotransmitter receptors found on the surface of cells; each receptor has a corresponding neurotransmitter.

Which part of the body does not feel pain?

The brain itself does not feel pain because there are no nociceptors located in brain tissue itself.

Where is pain felt in the brain?

The spinal cord carries the pain message from its receptors all the way up to the brain, where it is received by the thalamus and sent to the cerebral cortex, the part of the brain that processes the message.

What part of the brain detects pain?

Parietal lobe. The middle part of the brain, the parietal lobe helps a person to identify objects and understand spatial relationships (where one’s body is compared to objects around the person). The parietal lobe is also involved in interpreting pain and touch in the body.

Where in the central nervous system does pain perception occur?

There are multiple levels of CNS involved in the transmission of pain. These include the spinal cord (supraspinal), the brainstem (midbrain, medulla oblongata and the pons), and the cortical regions (cerebral cortex), as shown in Figure 1.

How can I test my nervous system?

  2. Electroencephalogram (EEG). …
  3. Magnetic resonance imaging (MRI). …
  4. Electrodiagnostic tests (for example, electromyography and nerve conduction velocity). …
  5. Positron emission tomography (PET) scan.

Which medicine is best for nervous system?

What medications are used to treat nerve damage?

  • Pain relievers.
  • Tricyclic antidepressants such as amitriptyline and desipramine (Norpramin), as well as other antidepressants, including duloxetine (Cymbalta) and venlafaxine (Effexor XR)
  • Certain anti-seizure drugs.
