There are so many moving pieces for neurology in medical school. The pace can be so fast, especially when learning it for the first time. If one doesn't understand a concept, a student is almost forced to make a decision that results in memorizing content when exams are nearing. I 100% believe that understanding the material is the best practice. You have taken the little pieces and put them together in a 17 min. video. Thank you so much. Sometimes I feel like I owe so much more to the teachers on RUclips than a simple like and subscribe. Please always remember that when I was worried and stressed about exams, I've found clarity within your videos. Thank you again. Keep up the great work!
SHING! The best anatomy lectures on the internet!
You chose to speak with the truth 🙌🏼
Sir you are the only teacher who teaches by knowing the mentality of students…such an excellent teacher…❤
Gods, your lectures have taught me more than my lecturers ever have. Thank you.
The most clear and fun video for explaining upper and lower motor neurons! Thanks!
Glad it was helpful!
The concept feels so difficult at first but it's so clear after watching the video. The quiz at the end reinforces the knowledge. Thank you so much!
Glad it helped!
Professor you are amazing. After 5 years in medical school and 10 years of practice in musculoskeletal, today I understood the concept and basic principles. It was shame that we were taught in such a difficult way. You made things so simple and easy that I started feeling interest in neuro patients.
Dear Shahzaib, thanks for your kind words. That made my day. I love MSK anatomy and had a lot of fun making the videos. All the best
Thank you so much for your selfless support, Dr. Morton. I'm medical school at University of Hargeisa Medical School, Somaliland. I took my neuroanatomy course last year and lectures about tracts was very difficult to me and I didn't get the concept correctly yet though I watched Dr. Najeeb's lectures. This's helped me a lot.
Same here
my future colleagues, inshAllah I will be working in Hargeisa
Your lectures are perfect for STEP 1
Thank you so much, sir. I'm in fourth year medical school and I confess I often have to go back and review my anatomy from time to time. Neuroanatomy, in particular, was something I struggled with back in first year. Your explanation is clear, succint, and of course, extremely helpful. Thank you once again.
Your anatomy videos are really the best on RUclips. I wish you were my teacher, you really have a gift for explaining things in a clear and engaging way. I don't know why some professors think that dry and complicated means smart... thank you so much. You're helping a lot of students all over the world.
I am a physical therapy student taking Neuroscience and this was extremely helpful after a confusing lecture just 2 days ago. Much appreciated Dr. Morton, keep them coming!
Absolutely incredible, I just watched the 5 brainstem videos and finally understand after weeks of pulling my hair out over neuro. Thank you so much 😭😭😭😭😭
So glad!
Liking and commenting on the video so that you get more energy to make more videos like this. Thank you for the video.
More to come!
These videos make things so clear! Thank you. Big fan of the application questions
no one:
Doc Morton: "shing!!!.. one more time shing!!!..." so much humor haha
Man this is just awesome, I am first year medical student and were struggling with this topic, books alone weren't helping much. Thanks for making it easier!!
This is best video on corticospinal tract on RUclips. I am so glad I found you. Goodluck. You deserve so many more subscribers
Thank you Dr. Morton! I am a PA student struggling though neuroanatomy and I am glad I found your videos. Not only are your explanations clear and extremely helpful, the way you present it is very engaging and fun to watch. Thanks again for creating these awesome videos and helping us students understand something we thought was difficult. We appreciate your work and would love to see more!
World runs on people like you. You are simply awesome!

Dr. Morton, you just made my class presentation so easy. I'm a psychology postgrad student in India, who's finding difficulties in Neuropsychology.

Extraordinary thanks, i am searching this
Thank you sir for this great explanation
thanks for making it much easy for understanding
The best video ever!
Thank u!
Amazing lecture as always, Dr. Morton, My only suggestion is in regard to your example, as you know better, spinal cord in adult end at the level of L1-L2 so we only have Lower motor neurons pathology if the damage is below L2 (conus medularis) and after this level, only Lower motor neurons run as cauda equina moving down through spinal canal to the respective levels for these neurons to leave the spinal canal and become the prespective nerve. othewise excellent presentation as always. Thank you
Excellent! Thanks a lot!
Very nice class
Aw yea, this is exactly what we need!
Thank you so much. This was literally so helpful.

Thank you so much!, you are awesome,!! saving med students all over the world.
P.s, is that you playing the guitar at the end?, it was super calming😌😌
Thank u Hope!
I am confused at your question at 14:45. The spinal cord in an adult ends at around L2 so how can you have the sections of the spinal cord going down through L4 and S4? Lesions at the L4 level should be all LMNs. Can you please clarify this for me?
The reason why is that the question was asking about spinal cord levels and not vertebral levels. The spinal cord ends at the L2 Vertebral level. However, the spinal cord still possesses all segmental levels (8 cerv, 12 thor, 5 lum, 5 sac) ... these levels are just compacted into the space between the C1 and L2 vertebral levels. If this is still confusing go to 3:01 on my Segmentation of the spinal cord video (ruclips.net/video/vbZZigN9qKQ/видео.html)
This is so amazing! Thank you
You are most welcome ... I hope it was helpful.
@@TheNotedAnatomist it's super helpful and very well organized.
EXCELLENT!!!
Amazing 🎉
Thank you ❤
You're welcome 😊
great lecture.
You the 🐐
Lesion above decussation contralateral side affected?
Love you so much!
Your videos are amazing!
This is a great video! Not sure if it was accidental to make the white matter grey and grey matter white :) but over all great explanation!
Taking ATLS course and it lists the coticalspinal tract method of testing by voluntary muscle contractions OR “involuntary response to painful stimuli”. From your video I get the voluntary muscle contractions but can you comment on that second part please.
Legend ... ary!
