Presents with pain Flashcards
What is the definition of pain?
- Unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage
- Occurs as a consequence of activity in a number of neural pathways
What factors can influence pain?
- attitudes and beliefs
- cultural factors
- psychological state
- social environment
- age and gender
Describe the mechanism of pain
- complex
- neural and chemical mechanisms
- impulse -> nociceptors -> dorsal horn -> ascending pathway (spinothalamic tract) -> brain
- also connects with limbic system (emotions)
- brainstem (ANS responses)
Describe nociceptors
- not all body structures have them
- may perceive mechanical, chemical and thermal stimuli
- are free nerve endings
- not all perceive all stimuli
- 2 types: A-delta and C fibers
Describe A-delta fibers
- large
- myelinated fibers
- quick - “fast pain”
Describe C fibers
- small
- non-myelinated
- slow - “slow pain”
List the types of pain
Somatic: • superficial -skin and subcutaneous • deep - skeletal muscles, joints, tendons, fascia • occasionally referred Visceral: • from organ • usually referred
What is referred pain?
- felt at a site different from its point of origin
- diffuse and poorly defined
- because the viscera synapses on same spot of dorsal grey horn as that skin
List examples of organs that refer?

Describe acute pain
- caused by injury to tissues

Describe chronic pain
• induced by injury
• long
• variable severity
• influenced by:
-type, frequency of stimulation, functioning of sensory pathway and higher centres
• accompanied by depression, sleep disturbance, anorexia
