Pain 5, Analgesic pathways

[@eva4basketball]

THE BEST VIDEO ON THE ANALGESIA SYSTEM ON YOU TUBE! Thank you!!!! :)

[@elainesmyth68]

hi john, I cant thank you enough, I was struggling trying to understand how it all works, you're a brilliant teacher

[@stefaniacosta4925]

The best professor on youtube. So clear,thank you!!

[@carolynvittle1989]

OMG we nursing students adore your lectures - thank you so much for all you do - one day when I am not a poor student anymore I will be buying books for you to gift forward most definately

[@crystalloney7586]

Thank you. This really helped me with understanding the Guyton and hall text explanation. I like to watch a video before reading the details. This one was great

[@Campbellteaching]

Guyton is superb

[@howardngo6459]

You are great teacher. I wish to watch your lectures 30 years ago. Very clear in explaining the concept. Thank you so much.

[@Gpacharlie]

Amazing insight at the end. The “patient” does mentally manage their chronic pain. If they “must” be somewhere or are responsible for someone they are “forced” to mentally manage the pain. Once the required activity is done the pain intensity increases. Of course this is often subconscious and an exhausting roller coaster.

[@guy_g704]

i literally mastered pain physiology by just listening to these videos.. asante sana sir.

[@Partycornchips]

Brilliant! This is the first bit of content I've managed to find on pain pathways that has been clear enough for me to understand! (Vet Nursing student here!)

[@Mazyone_]

thank you sir, I really appreciate your brilliant explanations. I wish I could meet you in the real world just to thank you. you are really helping me a lot with medical studies.

[@nellyhoffman6194]

thank you very much doctor ! god bless you !!

[@danielacatalancarcamo8268]

I was having trouble to understand this until i find this! Thank you very much

[@JessicaBlaisdell]

Thank you! You explain this system so clearly!

[@godfather297]

This is Gold . Great examples for better understanding

[@rishavkant8253]

Great lecture!! Can't imagine how simplified you made such a difficult topic

[@LogenBogen]

Thank you so much!!!! You're amazing dr!

[@edwardherrera4097]

Gabapentin does not bind to the GABA receptor despite the GABA in Gabapentin. It works on the Calcium channel.

[@greyline1012]

Thank you so much for speaking in laymans terms. I really do find these lectures insightful and interesting. Thanks Doc x

[@zacsamuel7295]

thank you for such a clear description

[@kasramd76]

Thank you.I am a pain specialist in Canada and I love the way you have simplified everything, your lectures has helped me better explain their pain and how nerve blocks I give them work

[@dr.akshayasharma1301]

Kasra Mike Haghighat hi

[@abdulahb]

You're amazing my sir! - Your student from the other part of the world!

[@Student.doctor]

Hats off to you sir you just explaned in amazing way 🙏💓

[@rakuldalsgaard5432]

You saved my life! I have an exam on monday, and this is one topic that i just didn´t understand! Now i fully understand it, so THANK YOU!!!!! :)

[@jkally1]

This is brilliant. I watch it at 2x speed for recap

[@jawharahh.5222]

That was super helpful, THANK YOU!

[@leesakura952]

amazing and super helpful thank you dr.john

[@rachelkenyon2836]

Wonderful!!!! Although if studying for pain pathways, you can start at about 3:45. Overall, such a clear tutorial!

[@hendokashaa6684]

THANK YOU SOOOOOO MUCH U R REALLY A GENIUS PERFECT TEACHER

[@TakeMeBackTo1986]

Thanks Doc! I was wondering how my Hydrocodone worked! :) Cheers!

[@makhosazanasibeko906]

[@Campbellteaching]

Excellent, keep going

[@user-hj7db3dl5w]

Excellent thanks for the effort

[@amalnemah3010]

It is an amazing explanation.thanks

[@bullseye9572]

Amazing,, thanks alot

[@shoshoa1101]

? could you talk more about how GABA affect inhibiting pain and thank you

[@user-vj8qm3qc2k]

thank you!!!

[@kamomamashela8994]

thank you...AWESSSOOOOOMEEEEE

[@yourfriendBJ]

Does the inhibition effect on the 1st to 2nd terminal create anaesthesia in all modalities of the spinothalamic tract?

[@mimizizi2373]

Thanks.. Merci ❣

[@ginavahle23]

By the way I am BSPT graduate and I am getting ready to take the NPTE. Your videos are of great help to me.

[@sarahbraga5589]

Thank you so much! I'm brazillian and it was very hard to find a video about endogenous analgesic system

[@Campbellteaching]

How easy did you find it to follow the language?

[@yaseenalhumry7385]

Great lecture thank you

[@adxphantom8257]

Thank you. :) I love videos like this

[@lolitaching5887]

cough

[@coolts93]

thank you dr

[@Summer-ch7sv]

Sir! Would you mind explaining disinhibition of the descending pathway please? Thank you!

[@nitinsingh7197]

Can you please tell how that descending pathway gets activated by electrical stimulation

[@zahraaahmed6194]

You are the best , thanx

[@Campbellteaching]

Thanks, do give me likes on as many videos as you watch, this really helps the channel.

[@wegdankalel2069]

thank you so much

[@fancraze5218]

Thank You Sir...

[@hendashraf833]

Thank you so much

[@kasramd76]

And yes, you have a gift when it comes to teaching😀

[@laibak2524]

Salam sir. Can you please explain where the pain signals are blocked in the diagram you drew first. Is it in the PAGM? And how?

[@hadilmab7353]

you are amazing Thank you so much

[@geojor]

thank you...

[@marvinoagare4853]

I would also be fascinated if I lived 9 years ago

[@ogooe1288]

Which is descending pathway of pain

[@peter357]

Fucking awesome, must link this to my professor :D That said, wish you mentioned if there is any other way to tap into this pain reducing system whiteout drugs...

[@mpachhangte9319]

Sir please reply as soon as possible. If the opiod receptors are present in the PAGM and other such structures involved in the Descending Inhibitory pathway, how does opioid administration stimulate the descending pathway. Shouldn't it inhibit it too by hyperpolarizatiin?

[@Campbellteaching]

Opioids will agonise the receptors in the pain inhibitory pathways. So opioids will increase the levels of depolarisation analgesic pathway neurones. This will increase the levels of neurological activity in the inhibitory pathways. As this increased activity inhibits the ascending afferent pain signals, the levels of pain impulses ascending to the thalamus is reduced.

[@Gpacharlie]

Dr. John Campbell I can testify!! Opioids are very important in chronic pain intensity reduction.

[@janakolosnjaj7054]

I love you

The sound of the marker is terrible. Lol. But thank you for a great video!

[@lenobenny1451]

Hi like u

[@elliotte4]

the mind is not contained in the brain. mind and brain are completely different no?

[@Campbellteaching]

+Ell English I think the mind is an emergent property of the brain. I believe this because when we turn down brain activity, with a general anesthetic, the mind is no longer aware. Consciousness and awareness are generated by the brain. Specifically, a lot of our consciousness is generated in the reticular activating system of the brain stem. I believe, that as long as we are alive, the mind, (what is us) is generated by the brain. These scientific statements make no comment on the mind being generated by an alternative agency. However, biological life is imaginable for our current scientific study.

[@Gpacharlie]

Dr. John Campbell They are no doubt integrated.
