Pain and language Flashcards
What are the 4 types of sensory receptors?
Thermoreceptors, Mechonoreceptors, chemoreceptors, and nociceptors
*Monitor temperature
* Located in the skin and in some parts of the central nervous system (hypothalamus and spinal cord).
*Help maintain stable body temperature.
Thermorecepors
- Monitor changes in the distortion of the cell membrane (eg. stretching and bending).
- Divided into 3 subtypes:
1. Tactile receptors
2. baroreceptors
3. proprioceptors
Mechanorecptors
What mechanoreceptor is for touch, pressure, vibration?
Tactile receptor
What mechanoreceptor is for pressure in blood vessels and vicera?
Barorecptor
What mechanoreceptor is for position of skeletal muscles and joints?
Proprioceptor
monitors changes in presure, found in blood vessels, heart (not on the skin)
Baroreceptors.
what are the 3 types of proprioceptors?
Joint capsule receptors, muscle spindals, Golgi tendon organs.
muscle spindle is a type of Proprioceptor responsible for?
Muscle length
Goldi tendon organ is a type of proprioceptor responsible for?
Muscle tension
Monitior changes in chemicals
chemoreceptors
- Detect potential or actual tissue damage (thermal, mechanical, polymodal)
- Found in skin, bones, skeletal muscles, less common in visceral tissues and organs.
- Free nerve ending.
Nociceptors
An unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage.
Pain
inspired by the biopsychosocial model of pain.
Onion skin model
Why do we need pain.
Avoid tissue damage, know when we need to rest
