How pain moves throughout the body?
4 process
Transduction: By needle=>Chemical mediators give signal to => muscle fibres also known A&C fibres=> send signals to the ganglion in spinal cord.
Transmission: Once pain in the ganglion than we secret neurotransmitter which take the message to the brain (particularly hypothalamus, sensory cortex, Limbic system) via afferent pathway.
Perception:
Modulation: this is where body naturally try to stop our pain by secreting enkephalins
Q: The stimulation of nerves that convey information to the brain about possible tissue damage refers to what?
