In this video, I draw out a cross-section of the spinal cord and describe the anatomy and some basic physiology that's happening there. This includes the regions of the gray and white matter, the dorsal root ganglia, central canal, ventral root, reflex arc, ascending tracts, and descending tracts.

At the start of this school year, I started taking anatomy and physiology. I immediately fell behind, and within two month I went from a A to an F. I found this channel TWO weeks ago, and after watching every single video on the anatomy and physiology playlist, I went to my teacher asking to reassess everything I had done so far, (my school has a endless amount of retake policy so I was able to reassess them all). After redoing every single test, (which took two weeks), I was able to return everything in. I just got my grade updated today, as the last thing has now been regraded, and I now have an A. And I am now one of the best students in class because of you. Can't thank you enough, and please keep it up!
what school do you attend that allows you to retake a test ? or help u get ur grade up ?
@@breonagreene5104ain’t no way that could happen in med school! 😂
Thank you so much, you saved my day. I'll recommend this channel to my classmates. More content please for anatomy and physiology. It really helps me as a nursing student.
Your videos line up to a T with my lecture classes. I love your videos, I love you
this is the best explanation of the nervous system I've seen. thank you so much.
Your explanation is so precise and clear❤
Sir you have changed my lifeee. Appreciate that so much sir. May you and your family receive all the love and success . Can you post about all the blood supplies of the body nerve supply arteries, veins? Its quiet challenging to remember
Thanks a lot for your time, courage and expertise! Best wishes
Incredible explanation. Thank you so much.
The best presentation lik all the time!
Stunning ❤
you are an amazing teacher youtube must give you an award..
you are great on teaching!!!
Your teaching method inspirers us, Thanks
Sir please make a video on Atrial and Ventricular pressure changes during cardiac cycle
Great video!!!!!
The best explanation thank you
Thank you SO much. Trying to revise (i.e. learn for the first time properly) neuroanatomy and this was so so helpful!!
You have such wonderful videos. I have both RMS and severe cervical stenosis (central and foraminal... going for a 4 level acdf next month); so, much of my spare time is spent studying.
Thank you so much sir have really understood 🙏🇿🇲
thank my teachar you crease my mind and knowledge
you are great!. THANK YOU SO MUCH
You're welcome!
Sir,
Can you make video on scapula and the major bones...your description is the best I have ever seen
I am studying in Medical College in India
You are amazing ❤ endless YouTubing of this topic your material has been the best
Thanks for sharing that! This video gets fewer views than I had hoped, so it’s great to hear it’s been helpful!
may I ask how you know all this stuff? you are incredible. I passed my midterm because of watching your videos, thank you so much for sharing your knowledge!
Congrats on passing your midterm!
I taught high school anatomy & physiology for about 10 years, so I learned a lot of it by teaching it. A lot of the videos I do now are on topics I’m less familiar with initially, so I have to read up on the topics and teach myself first.
regardless of how you do it, you do it well. I am thrilled I accidentally came across your videos and been a fan since. Next is a final in 2 weeks.@@SiebertScience
GOOD VIDEO
Thanks!
God bless you 🙏 abundantly
at 8.33 min, inter-neuron in grey matter -unmyelinated - crosses over to other side of the spinal cord, enters into the white matter and goes to the brain. Question: when in white matter and during its travel to the brain, is it myelinated or will it still remain unmyelinated?? some one please clear me of this doubt. thank you
Please sir, can you make a video on brachial plexus 🙏🙏🙏
Ur so so fantastic 🙏🙏
What app used for editing this video
I edited the video in Final Cut Pro, but the drawings were done in Doceri on the iPad.
Thanks. You really
Made my day
SIR if you can make vedios on pharam we will be greatful to you
What is pharam?
