If you don"t feel pain, it can be very dangerous to your overall health. Although not enjoyable, the experience of pain serves important functions: produces withdrawal that prevents future injury, serves as a basic of learning to avoid injurious objects/situations, sets limits on activity and enforces inactivity/rest for recovery and survival. Leading pain theory, has a few limitations. State that a gate-like mechanism in the spinal column"s dorsal horns controls: pain stimulation to brain. Is open/closed through central control activity in s. c. and brain: can increase or decrease the flow of nerve pulses, influencing the sensation of pain. Phantom limb pain: the experience of pain in a missing body part/limb. Gate theory posits that pain sensations: can be modified en route to the brain, can be influenced by psychological factors. Pain perception is part of a complex process that is affected by sensory input, n. s. activity, and past experiences.
