  1. Where in the body will you find nocireceptors?
    everywhere except the brain
  2. List the three types of stimuli that can activate a pain receptor.
    • mechanical damage
    • dissolved chemicals
    • temperature extremes
  3. Which type of pain travels over type A neurons?
    fast pain - prickling, lacerations, injections
  4. Which type of pain travels over type C neurons?
    slow pain - burning or aching pain
  5. Pain that is felt somewhere other than where tissue damage is located is called:
    referred pain
  6. Where would you find proprioceptors?
    • muscles
    • tendons
    • joints
  7. What is kinesthesia?
    the perception of body movements
  8. Where will the information from proprioceptors be sent?
    to the cerebellum
  9. True or False: Proprioceptors perform weight discrimination.
    True
  10. Which type of proprioceptor is commonly found in parts of the body that perform delicate movements?
    muscle spindles
  11. List the two functions of muscle spindles discussed in class.
    • monitor changes in muscle length
    • trigger the stretch reflex
  12. List the two functions of tendon organs discussed in class.
    • detect stress or strain on the tendon
    • trigger the tendon reflex
  13. Which type of proprioceptor monitors joint pressure?
    joint kinesthetic receptor
  14. Where are thermoreceptors located?
    • epidermis
    • dermis
    • muscles

    10o-40o C
  17. Which type of temperature receptors travel on slow, or type C, neurons?
    warm receptors
  18. Temperatures outside the range of temperature receptors activate:
    pain receptors
  19. Stretch receptors found in hollow organs are known as:
    baroreceptors
  20. What is measured by osmoreceptors?
    the concentration of solutes
  21. What activities will osmoreceptors control?
    • urinary systems
    • thirst centers
  22. Most body fluids have an osmolarity of:
    300 milliOsmols
  23. Chemoreceptors are sensitive to:
    dissolved chemicals in body fluid
  24. O2, pH, and CO2 concentrations are monitored by:
    chemoreceptors
  25. Which special sense do chemoreceptors play a role in?
    taste perception
