Spinal Pathways 4 - Corticospinal Tract

www.handwrittentutorials.com - The fourth instalment in the Spinal Pathways series. This video looks at the course of the corticospinal tract, from the Precentral gyrus to the peripheral muscles. For more entirely FREE tutorials and accompanying PDFs visit www.handwrittentutorials.com

Correction: not all fibers of the anterior corticospinal tract synapse at the contralateral ventral horn (via decussation at the anterior white commissure), some fibers actually synapse directly at the ipsilateral ventral horn. This is why lesion to this tract results in bilateral (although not obvious) weakness of axial muscles.

good correction

[@harinipreethi5932]

Thanks🤩

[@raghavym4964]

You should publish a book with your anatomical drawings and explanations!!! It would be a definite hit :)

[@JimitriG]

agreed, they are so helpful!

[@anandsingh4071]

Never seen a useful video like this..1000times better than boring n lengthy lecture of nazeeb

[@chadrichards4681]

Great series of tutorials, thank you so much. Gave me an excellent brush up for my neuroscience class!

[@MySeekingtruth]

Thank you for the clarity that is often so elusive with neuroanatomy!

[@aofainemullins7448]

Amazing- you have a true gift in your ability to teach. Thank you for sharing it.

[@mitotianiMartin]

I just would like to thank you for your amazing tutorials! You are a great teacher and also you draw very nicely! :-)

[@jennyinthemorning]

Hey, these tutorials are beyond helpful. Thanks so much!

In summary, the CST is a 2 neuron pathway, there is an UMN which arises in the primary motor cortex and a LMN which arises in the anterior horn.
The limb pathway (LCST) decussates in the pyramids in the medulla while the axial pathway (ACST) decussates through the anterior white comissure in the SC..

[@dannyt9429]

Thank you soo so much for making these! When I am done with school I will pay you when I'm working!

[@muhannadsami3270]

good idea.
don't forget this

[@milohuss6404]

So did you pay the guy

[@thephilosophersjourney2595]

You gotta keep your promise bro.

[@roaringsuccess2016]

@@milohuss6404 he probably forgot his password

[@buqbooQ]

bro needs to get paid

[@aaronlong7354]

Absolute gold for med students! Thank you!

[@ujalaalam]

Your tutorials are really helpfull. I learn by drawing the way you do and i never forget. In exams if i dont have enough time to write i then quickly draw and labell them and still get decent marks. Thankyou so much

[@alakkis6570]

Excellent videos!! Keep up the great work

[@nirzarinivora3750]

Absolutely brilliant concepts! These videos have been a life-saver! Please do a series on the Complement System?

[@m7amad2000]

You are totally fantastic. I thank you a billion of times!!!

[@cherryacaya5694]

I have a report tomorrow in our Neuroanatomy class about a case and your videos really helped me. Godbless! *subscrbed*

[@krassis6]

Incredibly clear and helpful. Thanks a lot.

[@Amstro515]

You really helped me a lot. Thank you so so much!

[@nareglaklakian]

you are a better hero than superman ...thank you

[@roaringsuccess2016]

who tf is superman lmao

[@Drunkenmoose]

I have never seen it so clearly put. Thank you :)

[@flawedpeanut]

I absolutely love these - wish there were more neuroanatomy tutorials.

[@ron0p0]

thank you very much.I ll definitely make contribution once I finish my med school and start working.Please continue your good work.

[@vishweshpatel1997]

best tutorials on youtube

[@KevyneShandris]

Keep in mind that any lesion along the Corticospinal tract -- especially involving the Posterior Limb of the Internal Capsule (PLOIC) -- can produce cerebellar-like systems (minus the truncal tribulations). Worse if it involves the Thalamus and the PLOIC not only the motor functions will be affected, the sensory functions can also be damaged.
I had a stroke involving both the PLOIC and the lateral Thalamus and now have unilateral ataxic hemiparesis with some sensory and visual problems (especially balance and temperature) due to it.

[@heavymetalcanuck6974]

Spinal pathways always confused me, now I get it! thanks so much!

[@zakijaved6368]

dayum man. you just killed it. thumbs up

[@angrant2014]

Thank you for simplifying it all!

[@nightwing255]

Thank you so much for this! Explained much better than my lectures! Making neuro easy

[@doubled6256]

Excellent video!

[@margaridateixeira6333]

I’ve been loving all your videos! You’re really helping me with Veterinary Phisiology. I just confuse myself sometimes with the anterior and posterior because it’s dorsal and ventral in veterinary ahahah

[@irenesilvernail6898]

Great stuff!! In 15 minutes I learned what I did not learn in a one hour lecture!
Wish I could donate now but still paying for school.
Hope to see more

[@sukhdev9411]

You can now

[@yaraa.4325]

Its so nice from you by doing this toutrial keep going on

[@yasminan.m3118]

you are a life saver thank you so much

[@diegocastroaviles336]

please do the trigeminal and cranial nerve pathways pleaseeeeee

[@vedashreeps9028]

Awesome video its so helpful and the handwriting its so understandable
😊

[@solivagant8291]

This is so helpful. Thank you!

[@elizabartsch]

You are amazing! These are so, so helpful! :)

[@sayeedhelal3600]

It is really awesome!! You did your best may be. I am a Master student of Neurosurgery, I believe, this will be helpful for all the students and even for the teachers who still do not know how to make it easy to their students.

[@CH-gb7hf]

thank you for the tutorial :) is it possible you to do a tutorial on the UMN and LMN lesions using this tutorial? Thank you !

[@maibanana1815]

I'm studying for my USMLE and the spinal tracts was really hard untill now.. thank you sooo much I can't believe that I finally got it.. wish u all the best ;)

[@buqbooQ]

10 years later you still getting it?

[@c9855296559]

love your tutorials. but hey is there any way you could upload the pictures of the graphics you draw? it would be really helpful while revising

Please do a video for the detailed anatomy of the brain.

[@zacbrown2196]

You are a god!

[@CarlyyCoCo]

Great video although just wanted to point out that some neurons of the anterior corticospinal tract have bilateral efferent output to axial muscles

[@maggiesmall5761]

YOU ROCK

[@rjb1122]

Great

[@triad6425]

OMG why couldn't I find an easy answer to what an upper motor neuron was. Awesome I am so glad I donated. After I get my next loan I am so donating again. Ummmm quick question how much would it cost for you to do a complete neuroscience course this way? And how long does it take for you to do a video properly. I wanted to do my own series for chem, physics, and pathology?

[@miadomidi3406]

When you done, show a full picture of slide please. ( to screenshot)

[@thefenerbahcesk4156]

Make a corticobulbar tract tutorial porfavor

[@neziheyanmaz2769]

correction: anterior corticospinal tract uncross whereas lateral corticospinal tract cross
