Document Summary
Processes included are: physiological, sensory, behavioural, cognition, discuss the neurophysiology of pain transduction (including the arachidonic acid pathway) transmission, perception and modulation. C-fibres: s, nm, slow speed: stimulation of different fibres results in different sensations. A-alpha/beta: nonpainful sensations such as light pressure to deep muscles, soft touch to skin, and vibration; a-alpha = sensory muscle, a-beta = sensory skin. A-delta: painful sensations such as prickling, sharp, well localised, short in duration. C-fibres: dull, aching, burning sensation and is characterized by its diffuse nature, slow onset, and relatively long duration. Normal processing of noxious stimuli by an intact nervous system. Somatic pain: arises from bone, joint, muscle, skin, or connective tissue: tissue innervated by the somatic nervous system, higher concentrations of nociceptors well localised, usually aching or throbbing. Abnormal processing of sensory input as a result of injury to the peripheral or central nervous system (damage to nerve cells or spinal cord processing)
