Just had a one hour lecture on this and didn't get it... 3 minuets here and it all makes sense. You are a LEGEND!

[@yulingtsui9419]

Ellos, just wanted to point out that there is a lateral tract which conveys pain and temperature and an anterior tract that conveys crude touch, which do not then synapse onto the secondary sensory cortex. Thank you for the nice summary! :)

[@madeleinemei-ling5625]

thank you. You made all my textbook readings come together in one handy video! much appreciated

[@milbobaggins88]

I have spent a semester learning the spinal tracts in depth and this has helped so much in clarifying everything and simplifying.

[@maybaby13x]

You are literally my new favorite person! My honors level neuroscience lectures are given by a respiratory physiologist who barely speaks English and just reads off powerpoint slides! You have saved me!! :)

[@ericsilvester7193]

Great Job guys! It helped me so much to get ready for the exams at the last minute! Please keep it up! Almost everyone in our batch used this entire set of tutorials!

[@goldwater9637]

I feel like some important parts were left out. If the first order sensory neuron synapses on the second order sensory neuron in the nucleus proprius, it will ascend contralaterlly via the anterior spinothalamic tract. If the first order sensory neuron synapses on the second order sensory neuron in the substantia gelatinosa, it will ascend contralaterally via the lateral spinothalamic tract.

[@The-Humble-Trader]

Can you please provide a reference for your comment! I could not find the precise division of fibers that you have stated in common anatomy books.

Thank you for your post! Projection to the thalamus: Neurons ascending via the spinothalamic tract synapse with 3rd order neurons in the following nuclei of the thalamus: Medial Dorsal (MD) (to the cingulate cortex), Ventral Posterior Lateral (VPL) (to the primary somatosensory cortex in the postcentral gyrus), and Ventral Posterior Medial (VPM) (to the insula).

[@uofagrad2009]

awesome job explaining this in a simplified and comprehendible manner! Similar to another user above I too sat through 2 hour lecture on this and was completely lost! Thank you for taking the time to do this!

[@kimberleyleatherwood3953]

I love these handwritten tutorials. It has helped me to learn them and to connect together the information I have learned in class. Thank you.

[@hanansiddiqui2024]

some incredible life changing content please keep creating 🙏🏻🙏🏻💖💖

[@EricDiazMD]

Although great, I think you should be more detailed. Thalamus synapses include medial dorsal, ventral posterior lateral, and ventral medial posterior nuclei. Neocortical synapses include cingulate cortex, the primary somatosensory cortex, and insular cortex respectively. The lateral tract conveys pain and temperature while the anterior tract conveys crude touch.

[@wojciechbogusz2239]

It's great for a quick review ;) got my anatomy classes in monday and definitely gonna watch it again. Can't wait to see the next part !

[@arielchasipanta2237]

You are the hero we need but don't deserve.

[@tonno88]

Great video, but you mention that the Dorsal Column/Medial Lemniscus is not a 3 neurons pathway, but it is: sensory fibre from dorsal root (1st) synapse onto gracile or cuneate nuclei in the medulla; these (2nd neurons) go up to the VP of the thalamus and synapse on thalamic neurons (3rd) that go up to the cortex...Keep the good work up

[@SecondDegreeMedicine]

I think he said 'and like' the dorsal column/medial lemniscus pathway...' might just be the accent sounds like 'unlike'!

[@minadz1279]

so sad you don't make videos anymore, handwritten tutorials is still one of my favourite channels I hope you're doing fine sir

[@HoneyyTeaa]

PLEASE go over the spinocerebellar tract if possible. Would greatly appreciate it!

[@venusgirafffe]

Watching this video can help me understand the key points that we need to pay attention on, which is better than reading books. Thank you

[@rasyid-mohammadtauhid-al-a5658]

For the non-English teaching environments the video can be cropped to produce ppt files for lecturing, or dubbed the narrations totally. Worldwide supports and other submitted topics hopefully will make health sciences educations even better and more efficient by making respective students study the topics easier.

[@hacantyapradipta1119]

The thing is, I think most modern medical study are using sources (Books, videos, journals, websites) in English, no matter which country.

[@lostinthoughts13]

Enters the dorsal root, moves up, synapses with 2nd order neuron, moves to the other side, then up to the thalamus where we have the 3rd order neuron which goes to the somatosensory cortex.

[@cyberwarrior7494]

THANK YOU

[@georgegrama6724]

thanks for the videos.. GREAT ! one suggestion please: at the end of the video, please zoom out, so we can take a screenshot of the whole lesson, for better overview :) thanks again

[@gondoyinfante7315]

@ around 2:50 mark -- Just want to clarify, as what I have learned from this video and from the previous one that Dorsal-medial lemniscus tract and the Spinothalamic tract both are 3 Neuron pathways: DML tract, 1. dorsal root ganglia 2. medulla oblongata (gracilis/cuneate nucleus) 3.thalamus; Spinothalamic tract, 1. dorsal root ganglia 2. dorsal horn of the spinal cord 3. thalamus.

[@drtiarafazlin]

When u said this pathway is unlike dorsal column, isn't dorsal column medial lemniscus has 3 order neurons too? 1) Dorsal root ganglion 2) Cuneate\Gracilis nucleus 3) Ventral Posterolateral nucleus

[@MiLdIzz]

Suruh Haji J surf G+ saya... FB dah "HOLD" saya for identity proven... :D

[@salmaabdelaziz4934]

Tiara Fazlin I think he said "like" though.

[@gobimuru]

Tiara Fazlin That's what I thought first but listening to it again, he said 'and like'

[@Camm13723]

its different because the pathway crosses over in the spinal cord. In the DCML pathway, it crosses over in the midbrain at the caudate medulla

[@Android18uk]

This is really good.

[@richardchoongmingslater6100]

When you say they ascend through their respective tracts, are you referring to the Lateral Spinothalamic tract or the Anterior Spinothalamic Tract? or both?

[@miancu3]

Either one

[@amagudgurl1000]

@@miancu3 anterior = crude touch lateral = pain and temperature

[@ningan9956]

Your video is absolutely helpful!!!!!!!!

[@meneshkaponnampalam8129]

Hi, thanks for the video - very informative and really helpful! Just wondered about lesions of the spinothalamic tract - am I correct in thinking that this would cause ipsilateral and contralateral damage depending on where the lesion is i.e. whether the 2nd neurone has decussated yet after ascending/descending?

[@enesdemiryarar7016]

I want to watch more tractus from you like tr. spinoolivaris, tr. spinocerebellaris ant/post, tr. spinotectalis ext. Your videos are so good thanks for that.

[@mirandababbitt8337]

[@thebittersweetmyke1]

you said unlike the Dorsal column-medial lemniscus pathway that this pathway is a 3 neuron pathway (2.49) .isnt the Dorsal column-medial lemniscus pathway also a 3 neuron pathway??

[@johnmikhail8059]

The dorsal root ganglion is not a synapse. The pathway includes 2 synapses and thus 3 neurons are involved not 3 synapses as mentioned.

[@triad6425]

I LOVE THIS ONE THANK YOU.

[@sleshabhalja7318]

crystal clear!

[@daniellescandal2768]

Is there a video on the spinocerebellar tract? These are really helpful!

[@badboys0155]

watch dr najeebs lecture on ascending tracts.... one of the most helpful material on net...

[@Alessiaandanowl]

He does on the website

[@antonella9713]

In 2:50 it says and 'like' and not 'unlike' right? because both are 3 neutron pathways!

[@SecondDegreeMedicine]

At 0:57, you say that it ascends or descends... I thought it was an ascending pathway? and wouldn't descend! Confused now... Do you just mean that it might ascend or descend Lissauer's Fasiculus before then decussating and then ASCENDING upwards to the thalamus? Why do some ascend and why do some descend before then ascending? Thank you for clearing up any confusion. Thank you for the hard work!

[@MiraCheskis]

As it was explained to me, it can either ascend to synapse or it can descend to synapse.

[@SecondDegreeMedicine]

Rose Lovell Thank you. :)

[@khalidbashir1989]

by ascend and descend he means that some of them carry information that goes from the body to the CNS and these are ascending information carried by ascending tracts and they are sensory informations, the others which are termed descending are tracts which carry information from the CNS down to the body and these are usually motor...so the nomenclature of the tracts is based on the direction of the information they carry.hope that helps

It decussates to the white matter (corticospinal tract) not into the gray matter. The cell bodies are in the gray matter.

[@thomasanderson1416]

This is the same as extralumniscal pathway right?

you said this pathway unlike the dorsal column medial lemniscus pathway has three order neurons ? do u mean unlike the spino-cerebellar tract or I miss understood the dorsal column pathway ?

he showed it in the first video :)

[@racimbouhadji7327]

not enough and too general , my teachers make it so detailed , that this is not enough and sufficient to pass .but thank , great job . PS: lateral and anterioir spinothalamic tracts ,the lateral vehiculate the pain & sensation and the anterior the pain and temperature , but they terminate in different nuclei in the thalamus , pain goes through the cm and dm and finally in the frontal cortex and the touch and thermal sensation in the VPL . ;) good luck for those who have exams like me

HI!

[@Doctor_House_MD]

😊😊😊

[@johntaylor8271]

The substantial gelatinosa is the spinal trigeminsl nucleus and Lissauer's tract is the trigeminal tract and the dorsal horn is the trigeminal (medullary) dorsal horn all of which was readily acknowleged in earlier science until the they started pushing their fake vagal nerve stimulation hype so over time they eliminated the word "trigeminal" in the spinal column to keep you from finding out that CN V is not only the principal regulator of the sensory modalities of the head but also the body. Throw away all your books, studies and articles post 1990 and only ready the earlier versions pre 1990 to learn the truth. The earlier editions the better because the authors were on big pharma payroll to push the lies. I find the first editions dated in the 1960's the best. Ever since science was coopted by big money and big pharma it's garbage only to push false narratives like VNS to make $$$ Also, the spinothalamic tract and medial lemniscus are part of the trigeminal system. The trigeminal lemniscus is the head of the medial lemniscus. That's why they changed the name of trigeminal lemniscus to trigeminothalamic tract to keep you from connecting the tracts.
