Neuroanatomy

  1. Major types of somatosensory receptors.
    • 1. Mechanoreceptors
    • 2. Thermoreceptors
    • 3. Nociception
  2. What information does the anterolateral system carry?
    • 1. Pain
    • 2. Temp
    • 3. Crude touch
  3. 2 types of pain
    • 1. Fast pain
    • 2. SLow pain
  4. Fast pain ( makes up anterolateral system)

    1. carried by _____ fibers
    2. Terminate in ________ fibers
    1. A-delta fibers (type III)

    2. laminae I and V
  5. Slow pain
    1. carried by _____ fibers

    2. Terminate in ________ fibers
    1. C fibers (type IV)

    laminae II and III
  6. Both pain pathways use _______ and _____ as neurotransmitters?
    1. Glutamate

    2. Substance P
  7. Anterolateral system made up of 3 pathways
    1. Spinothalamic

    2. Spinoreticular

    3. Spinomesencephalic
  8. Spinothalamic pathway: fast pain. Describe the location of neuron order

    1st order neuron
    2nd order neuron
    3rd order neuron
    1st: A delta fibers with cell body in DRG

    2nd: Cell bodies in Lamina I and V, cross in ant white commisssure

    3rd: VPL of thalamus, to postcentral gyrus via post limb of internal capsule
