Nociceptive pain consists of an adaptive alarm system. [6] Nociceptors have a certain threshold; that is, they require a minimum intensity of stimulation before they trigger a signal. Once this threshold is reached, a signal is passed along the axon of the neuron into the spinal cord.
The experience of pain is individualistic and can be suppressed by stress or exacerbated by anticipation. Simple activation of a nociceptor does not always lead to perceived pain, because the latter also depends on the frequency of the action potentials, integration of pre- and postsynaptic signals, and influences from higher or central processes.
Other factors affecting the perceived level of danger and spatial awareness further complicate the model.

These can be released in response to a number of things, including increased blood pressure, pain and danger. It has been found that endogenous opioids are at least partially responsible for phenomena like " Runner's high ", hypoalgesia in the fight-or-flight response, and even for the analgesic effects of acupuncture therapy.

Through their life experience, individuals learn the concept of pain. A person's report of an experience of pain should be respected ...
It is clear from this definition that while it is understood that pain is a physical phenomenon, the emotional state of a person, as well as the context or situation associated with the pain also impacts the perception of the nociceptive or noxious event.
