    Sir I've never - in nearly 30 years of practice in the direct realm of pain- seen a more succinct yet understandable explanation of the ascending pathway .... and in 12 minutes !!!
    You Sir have a gift

      At first sight the study of human anatomy may appear very difficult. It is tru?e that it is not simple and your studies wont change that. As for being overwhelming, this can be solved if you take it one step at a time. I found an article on Sebs Study Crammer very useful for this.

    I liked the way you gave an overall introduction to pathophysiology of pain, and what I truly liked is that you draw structures that can enhance our understanding and give us an insight about where exactly does pain processes happen through numerous pathways

    I appreciate this video as the *survivor of a spinal injury* (L1 compound fracture) resulting in 2 pain disorders (central + CNS pain syndromes) & a related sleep disorder (narcolepsy). I've lived with relentless pain for 14 years, since I was a teenager, & have no hope of achieving any meaningful relief, but I still want to understand as much as I can.

    2) A-DELTA AND C FIBERS IN SOME PARTS OF SKIN,MUSCLES, VISCERAL TISSUES,

  • @havealookaraound
    @havealookaraound 10 років тому +18

    ONE mistake, the spinothalamic pathway for pain travels up the LATERAL branch, not the anterior as shown (touch and pressure are anterior, pain and temp. are lateral), however AMAZING work and I'm learning faster than ever with your work :) a big thanks.

    • @nokialover31
      @nokialover31 10 років тому +8

    • @11shardy
      @11shardy 10 років тому

      ***** Correct me if I am wrong, but doesn't the anterior spinothalamic tract carry pain fibres for everything other than information from the limbs? If I am correct, then this would indeed mean that the information in this tutorial is actually correct!?

    • @xDomglmao
      @xDomglmao 7 років тому +1

      I think it's correct for a 'softer' kind of pain only; I'll check again in the Snell (neuroanatomy) once I passed everything :D

      I accept what you have written - definately not as easy than some people make out to treat neuropathy at home.
      Be cautious and take advice from other people. I searched round many websites and found some expert advice by searching google on sites like Gabs Neuro Guide. Good luck and hope you succeed!

    • @Garebare24
      @Garebare24 8 років тому +29

      That would take 30 seconds: Pressure and fine touch sensors share the same tract as pain travelling through the spinothalamic tract (either anterior: fast localized or lateral: slow unsure throbbing). Since they converge on the same Dorsal horn on the spine, if you rub a hurt area after scraping your knee, the fine touch Limenscal Tract fires like crazy effectively "taking over" the pathway with more touch going in the dorsal horn than pain. Think of it as narrowing a door in a movie theater filled with obese people where the obese people are pain and the door width is stimulation of touch via the limescal tract. If you narrow the door, the obese people would take forever to get out because they are so big and the door is so small. Widen the door (by stop rubbing the effected area) and all the obese people (pain) can exit and pain is recieved in greater magnitude.

  • @mourilshah2054
    @mourilshah2054 6 років тому +2

    You could've been more specific and could've edged that extra information up the video
    Pain pathways are ascended through lateral spinothalamic tract and crude touch sensation is through anterior spinothalamic tracts .
    These fibres ascend in such a way that they are called anterior lateral pathways in general.
    Pain fibres (Muscle spindle,Golgi tendon organ,pressure receptors ) from the periphery ends up to Substantia Gelatinosa (lamina 2) and Nucleus proprius (lamina 3 and 4) and first order neuron terminates here
    By the way ,the video was good

    I think Both A delta and C fibres are unmyelinated .they are the lateral division of dorsal root ganglion.
    On the other hand, A alpha, A beta fibres are myelinated large and belong to medial division of DRG.

    A fantastic overview, both to introduce and help revise the basic mechanisms. Just one question: are you planning to also follow on from this introduction to cover the nociceptor pathways in more detail, e.g. descending modulatory pathways, the role of PAG and lamina II cells?

  • @hazzae
    @hazzae 11 років тому

    Excellent video. One minor thing. Melzak and Wall's gate-theory of pain doesn't involve the descending inhibition mechanism but local mechanisms in the dorsal horn . Remember also that pain and nociception are related but different things. Nociception is neither sufficient or necessary to create pain.
