response to pain

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a pain stimulus. Pain stimuli cause activation of nociceptors, peripheral receptors for pain, include receptors which are sensitive to painful mechanical stimuli, extreme heat or cold, and chemical stimuli.

behavioral response to pain

Any process that results in a change in the behavior of an organism as a result of a pain stimulus. Pain stimuli cause activation of nociceptors, peripheral receptors for pain, include receptors which are sensitive to painful mechanical stimuli, extreme heat or cold, and chemical stimuli.

sensory perception of pain

The series of events required for an organism to receive a painful stimulus, convert it to a molecular signal, and recognize and characterize the signal. A painful stimulus is any physical or chemical event that has the potential to cause tissue damage (actual or perceived) and activates the nociceptive system.

detection of electrical stimulus involved in sensory perception of pain

The series of events that contribute to the perception of pain in which an electrical stimulus is received and converted into a molecular signal.

detection of temperature stimulus involved in sensory perception of pain

The series of events involved in the perception of pain in which a temperature stimulus is received and converted into a molecular signal.

detection of chemical stimulus involved in sensory perception of pain

The series of events involved in the perception of pain in which a chemical stimulus is received and converted into a molecular signal.

detection of mechanical stimulus involved in sensory perception of pain

The series of events involved in the perception of pain in which a mechanical stimulus is received and converted into a molecular signal.

sensory perception of fast pain

The series of events required for an organism to receive a fast pain stimulus, convert it to a molecular signal, and recognize and characterize the signal. This is a neurological process. Fast pain is often subjectively described as a sharp or stabbing pain; in humans, the signals from a fast pain stimulus are perceived and relayed along myelinated A-delta fibers to the central nervous system, reaching their target in about 0.1 seconds.

sensory perception of slow pain

The series of events required for an organism to receive a slow pain stimulus, convert it to a molecular signal, and recognize and characterize the signal. This is a neurological process. Slow pain is often subjectively described as an aching or throbbing pain; in humans, the signals from a slow pain stimulus are perceived and relayed along unmyelinated C fibers to the central nervous system, reaching their target in about 1 second. Slow pain is often associated with tissue destruction.

behavioral response to chemical pain

Any process that results in a change in the behaviour of an organism as a result of a chemical pain stimulus.
