Thank you so much for your efforts. I am a Neuropsychologist, and spent a lot of the 90's learning neuroanatomy from textbooks. What a luck people have today. Even for me, it makes me want to see the videos, and then review the books, but now with an "unfair" advantage. You can't imagine the difference this would have made for me back in 1999...
This was an excellent video on a very complicated topic! I have already watched it three times and i will return back to watch it again. There is so much information jam packed, that it needs to be reviewed many times for most of us, but you broke it down in a way that was easy to understand which is extremely difficult due to the complexity of the topic! Thanks again for all your help Ninja nerd!
You are a Life Saver!!! I understand this stuff when YOU explain it! I come away with a clear understanding of how the systems fit and work together! I'm not saying my instructor is a bad teacher, he's a great guy actually, but he is so hard to follow. Thank you so so much for your lessons... There is hope for me!
Can’t believe you guys crossed 600k followers!! I’ll pray for this channel’s growing success and I hope it crosses 1M soon . Love watching NinjaNerd Lectures grow!!
you know how to explain and teach other people and make them understand and remember at once .Your explanations are the best and easiest for us to understand. I like the way you explain from the basis and go to advanced information. Thank you very much for sharing these videos to public. You are a hero for medical students like us because you make us be able to save money and time to buy and read those heavy medical textbooks. I wish the lecturers at my uni were able to explain like you do. Thank you!!!
Currently studying for my neuro exam for medical school and was struggling with this topic. However, your explanation was super helpful and easy to comprehend!!!! Thanks!
You're awesome!! You should make papers for download, with the sketch on the whiteboard before you draw anything on it, so one can draw along with you at home!! :D
thank you so much for making the spinocerebellar tracts sound like a breeze!! always used to mess them up, but this has really made it super easy to understand!
Dorsal (posterior) spinocerebellar tract The primary function of the dorsal (posterior) spinocerebellar tract is to relay cerebellar tract proprioceptive input from the neuromuscular spindles and GTOs of the ipsilateral trunk and lower limb, to the cerebellum. It should be recalled, however, that it also relays some touch and pressure sensation from the skin of the ipsilateral trunk and lower limb. First order neurons (pseudounipolar neurons) whose cell bodies are housed in the dorsal root ganglia send their peripheral processes to the skin, muscles, tendons, and joints. Here they perceive proprioceptive information, which is then transmitted to the spinal cord by their central processes. These central processes join the medial division of the dorsal roots of the spinal nerves to synapse in the nucleus dorsalis (Clark’s column, lamina VII of spinal cord levels C8 to L2, 3) at their level of entry. Sensory information transmitted by spinal nerves entering at the sacral and lower lumbar spinal cord levels (below Clark’s column) is relayed to the caudal extent of the nucleus dorsalis (L2, 3) by ascending in the fasciculus gracilis. Clark’s column houses the cell bodies of second order neurons whose axons form the dorsal spinocerebellar tract, which ascends ipsilaterally in the lateral funiculus of the spinal cord. When this tract reaches the brainstem it joins the restiform body (of the inferior cerebellar peduncle), and then passes (as “mossy fibers”) into the vermis of the cerebellum. The dorsal spinocerebellar tract relays proprioceptive information directly to the cerebellum where this information is processed; it plays an important role in the fine coordination of movements of individual lower limb muscles or synergistic muscles controlling movement of the same joint and in the maintenance of posture.

@@xDomglmao Do not confuse with spinal cord segments for vertebral level. Conus medullaris ends at L1 level which corresponds to spinal segment coccyx 1
@@shanartz8152 Thank you! I checked 5 different sources and all were not precise but it makes sense how you explained it! :) Enjoy your day EDIT: So I checked the pictures and please correct me if I am wrong: I was told by my teacher today that Clarke's column ends with the SC (which would mean vertebra L1); but when I checked which spinal segment this equals, it says T11 - so if I compare this with what you suggested initially (that the books' "L3" were referring to spinal segments rather than vertebra, which initially made perfect sense) it doesn't work out anymore :/ So either I misunderstood my teacher or something still not ok :/ EDIT: Fuck, man, you are right! Thx!
Wow, simply amazing, I am in love with this man for his knowledge and extremely Supreme skill of being errorless, simple sweet straight to the point...I can binge watch this whole Playlist! Thank you so much sir❤ God bless you
wow you truly saved me from a meltdown!!! Thank you are great! I wouldn't mind if you did more videos on the Motor Neuron Pathways or anything Neuroscience related.
