Im curious how many people use this for PA, Nursing school, med school or any other advanced school. You are a life saver

These are wonderful! I am a first year vet student and I use these as quick reviews to give me a general framework for all the other details I'm learning! Very helpful - and beautiful artistic work!!!

If only the teachers and professors in medical colleges teach like this... You are doing an awesome job Sir😎👍

"So i hope that makes sense" seems to be your favourite sentence :D

on behalf of all students studying medicine, thank you tremendously for all of your videos. God bless you.

Can't explain enough how useful the videos are! Such a great work plus explanation is to the point 👌 Thanks much great work

Have a test tomorrow and watching this video really helped! Thanks a bunch! Keep up the amazing work!

I have notes regarding this video Corticospinal pathway decends through the internal capsule not thalamus, Anterior corticospinal supplies proximal muscles bilaterally

Professor Frink gave me a good understanding of the basis of structure and function of spinal cord. The lecture is well oganized and thank you Dr. Flint.

Your lectures are so clear...blessing for medical students..

First year undergrad med student, and this vid saved my life haha. My finals are in a month and I was too lazy to study neuroanat until last minute, only to realise I didn't know what was going on at all. Your video really helped a lot, thanks! :)

I am a biomedical engineer interested in stroke rehabilitation, this was one of the well explained videos for motor pathways

where is the video for ascending and descing tract ?plz give me the link of ur video

Man, you're AMAZING. Your videos are so helpful. Thank you so much!

Your video saved my studying life in biology. This is awesome. Please do more.

WOW WHAT A LIFE SAVER, THIS IS SO CLEAR, PLS DO MORE from stressed medical student

You made it sound so easy!!! Thank you very much! keep the good work

This helped me so much! For my upcomming exam we need to draw this too!

BLESS YOU you literally saved me HUGE props to you and THANK YOU!!

mesmerizing and informational at the same time.

Thank you for this video....... I love watching this....... I will watch it again and again...... Really it helps me in my goal in life to pursue my dream course.....

Very helpful video for my Physiotherapy studies, thank you!

2021 anyone? Love u man, im watching u from my high school to medschool, through and through, beautiful work u have done, and thanks for making these vids, wish u the best of bests

A very good video! I am studying pshychology and this helps me a lot! Thank you

corticospinal tract don't pass through the thalamus,it passes the posterior limb of internal capsule

Thanks !!! u saved me ....ur videos are just superb, all of them. Big thumbs up!!! God bless u.

Thank you for your help and time! Amazing explanation.

Hello! Where can I find the previous video about the sensory pathway? I'm really struggling to put all these concepts together so it'd be a great help. Thank you so much! :)

Motor Control Theories please !!! Great work, your always my to go to reference for info on Neurology !

Motor pathways can be divided into Lateral pathways & Anteromedial pathways Corticospinal tracts most important coz they deal with voluntary control. Lateral Corticospinal tract Anterior Corticospinal tract Rubrospinal tract Anteromedial pathways : mainly controls axial muscles for balance and posture. Tectospinal tract: originates in the midbrain in the area ka Superior Colliculus. Responsible for orientation response. Reticulospinal tract Vestibulospinal tract : responsible for maintaining head balance and turning. Anterior Corticospinal tract

THANK YOU ARMANDO!

Not only ur drawing but your explanation are so good

You are the best man!! Thank you for your videos... Adamın dibisin dibi

you have been the best help! thank you!

your videos are amazing. thank you so much cx

also you fail to mention in the lateral tract pathway, it has the reticulospinal lateral tract and lateral vestibulospinal tract, it is not only anterior pathway as you mentioned in your video. Reticulospinal lateral medullar tract inhibits Involuntary excitatory extensor muscle movement and decreases muscle tone, pontine/medial reticulospinal tract increases involuntary muscle tone and increases extensor muscle activity

Amazing video! Thank you

lateral corticospinal tract doesn't pass through the thalamus😑 it goes into posterior limb of internal capsule

Rubrospinal tract is an alternative voluntary spinal motor tract, not only manages large muscle movement is also involved in fine motor control of upper limbs such as grasping objects but not individual finger movement, this is the particular feauture of the corticospinal tract, also it is involved in rapid movement of muscles, it is constantly limited by the corticospinal tract, that is why if they cut the corticospinal tract, rubrospinal takes over and can manage to recover 90% of voluntary muscle movement except individual finger movement. It controls flexor muscles, it limits extensor muscle movement, and yet you only managed to say it is important instead of providing more information.

difficult stuff made so easy, thank you!

Love your videos dude...

Glad you fixed the lighting in your videos =)

thanks ,, keep taking about neurology

The red nucleus & the rubrospinal tracts are involved more in coordination of upper limbs, not the entire body. That's why in decerebrate rigidity, the upper limbs are flexed because of loss of rubrospinal control.

excellent drawings and explanations

Very helpful video!! Thanks a lot!!

Nice video! Great rookie learning material!

so nice of you

lmao. Earlier today I searched for a video on the motor tracts on your channel. :P

Thank you so much 🙏🙏🙏

In your video you say anterior corticospinal tract control proximal muscles such as the arms, but I have learned in various medical books that anterior corticospinal controls only muscles of the trunk (Thoracic and abdominal cavity), lateral corticospinal tracts control upper and lower limbs muscles including arms.

Thank you sir to teach motor pathways&tracts

How the hell do nursing and med students learn all this, just on the nervous system then the rest of the anatomy of the body. It’s amazing just watching you draw all this out.

awesome and very helpful lecture. how dare those 8 people who dislike this video lol

Thank you sir 💟

Where are the descending and ascending tract videos you mentioned in the beginning of this video?

Perfect timing. Neuro exam on monday

Great explanation

Thanks armando !

I was under the impression that a lesion of the lateral corticospinal tract will cause a deficit on the ipsilateral side of the lesion, because the LCST begins below the decussation in the medulla. The contralateral hemisphere of the cerebrum controls the motion, but if a lesion occurred in the LCST, the deficits will show on the ipsilateral side of the lesion.

where can I find the video he references in the beginning of the video about the "Introduction to the descending and ascending tracts?" I cannot find it

I can't find the video of descending &ascending tract, any one help ? Armando could you pls put the link of the videos you talk about in bio next time!

Neurophysiology made easy ,thank you.

Thank you !

What are the neuro trasmittis response for your fast and slow pain ? its amazing . I love it.

you are great sir nice lecture

great job

Great videos, thanx! But I'm a little confused. Where does the autonome motor neurons fit in? In your other video of the overview of the peripheral and central nerve system you describe motor neurons are either somatic (voluntary) or autonome (not voluntary). But I think al these tracts shown here are somatic tracts? Because autonome neurons use ganglions and have other functions. And the anteriormedial tract is not voluntary, so to equal somatic with voluntary is not really correct? Or what am I not understanding correctly?

A minor correction : corticospinal tract does not pass through thalamus. it goes directly to midbrain via cerebral peduncles.

Many different motor pathways that extend down through the spine.

Thank you so Much!

that's very useful for me ,, thank you

I thought the spinothalamic pathway doesn't pass through the thalamus, but passes through the internal capsule? Reference to 4:25

THANK YOU

VERY VALUABLE CONTAIN THANKS

So the anterior corticospinal tract does not dessucate in the lower portion of the medulla, but does that in the anterior horn? so ipsilaterally down until the anterior corticospinal tract before it dessucates to the ventral horn contralaterally where it synapses?

Thankyou

what pens/markers are you using? thanks!

It was very helpful

THE BEST🙌🏼🙌🏼🙌🏼🙌🏼

What is the role of the upper neuron in the motor pathway: 1. Transfer impulse from motor cortex to spinal cord 2. Transfer impulse from spinal cord to motor cortex 3. Transfer impulse from spinal cord to muscle 4. Transfer impulse from muscle to spinal cord

should notice that 5% of spinocortical tract fibers do not decussate and called "non decussated lateral corticospinal tract" and 5 % representing the anterior corticospinal tract are actually decussating twice, once at the medulla oblangata and once again at the level of the specific vertebre, there for innervating eventually in an ipsilateral manner. and third the upper motor neuron does not pass through the thalamus but through the internal capsule. anyway it's a great video thanks

well i found this like d-1 the exam, but thank you so much!!!

Upper motor neurones do not send axons into/through the thalamus.

Where are the descending and ascending tract videos you mentioned in the beginning of this video? requesting you to load more on maintenance of tone and posture and balance.

thank you

Great video. I have a question, isn't it that the corticospinal nerve's path is in between the thalamus and the lenticular (internal capsule) ?

You forgot the olivospinal tract that some scholars put in the anterior/ventromedial system, other do not include it as part of this system. It would have been very helpful if you explain the tracts that deccusate and why tracts that deccusate cause opposite side lesions in upper motor neurons and same side lesions cause same side affections in lower motor neurons, this was not fully explained, also you must include the corticobulbar system, it travels along with the corticospinal tract but deccusates at different levels of the brainstem.

I wish you could upload the whole page at 12:24 as a picture. That would be awesome !

Can someone tell me where to find the Introduction of Ascending/Descending Tracts video at the beginning?

hi there, great vid, but we've been taught all 3 medial pathways (inc the tectospinal tract) are ipsilateral..... i will look it up. I'm too grateful to be critical if you got it wrong. Good work.

Thanks a lot

hi, can I ask you a question?so both ANt and Lateral cortico spinal tract cross over and control the muscles on the other side ? just the location of cross-over is different?can i say if lesion in in upper motor it always affect contralateral and if in lower motor it affects the same side ?

The best!!

very beautiful sir

Neuro exam this monday, thanks for the vids man!

At 1.00 you mentioned that the outer grey matter of the Cerebral Cortex consists of synapses. Shouldn't it be neurons and correct me if I'm wrong? Jackson, Mississippi.

Is there a place we can buy this exact image?

Thanks
