Some heroes don’t wear capes. You are a superstar, Zac. Thank you for making me pass physiology, med school would be considerably harder without you!
Your neurology play list makes me stay ahead of my class. Much love zach

Extrafusal fibers connect with tendon.... and intrafusal fibers connect with??

@Marco Di Paolo intrafusal fibres,are modified muscle Fibre so I think the are connected in the same way and change their length with the whole muscle.
Hey Zach. In your older videos you used to put the entire whiteboard on the screen for a couple seconds at the end of the video. It really helped for revision. Can you start doing that again please?

your an amazing human for how your helping us med students , alot of med unis never bother to upload decent slides or lectures to explain anything so thank you for what your doing to help us students become what we want to be
I´ve been struggling with physiology the whole semester and you saved me. Thank you so so much for your videos!
I love your passion for the content as it allows a guy like me who is ADHD grasp such high yield info in fun way! I will never forget the alpha-gamma-coactivation because I know when those nuclear bag muscle fiber endings contract those Type I-A sensory neurons are activated because, "they tight baby!"
Thank-you! I have watched a lot of your videos and they immensely helpful with a touch of humour. I know some doctors teach so imagine you will be teaching at a university if not already. Your videos are medicine as they help me to understand which relieves exam stress and lowers blood pressure. :) The world needs more people like you.
Finally this video cleared my concept of stretch reflex that was bothering me a lot , love and respect from my side 🙏
Thank you so much for these lectures. Im in medical school right now and I use these lectures to better understand whats written on my very very complicated Physiology textbook. Cant stress it enough, THANK YOU 💯
Right on time for my MSK/Neuro test. You're the man ❤️

Hi .. I follow you from Syria. I get a lot of benefits when I saw your videos about nerves and after it I started to follow. My English isn't perfect but I could understand you . I hope one thing to be more clear when you talk because our mother tongue is Arabic and your videos make the subject easy . Thanks and hope to read my comment.
Thank you so much.tomorow is neuroanatomy exam, really this lecture id helpful.
Superb explanation. Thanks
Spinal cord reflexes are simple behaviors produced by central nervous system (CNS) pathways that lie entirely within the spinal cord. The sensory afferent fibers that evoke these reflexes enter the spinal cord and activate spinal motor neurons directly or through a chain of one or more spinal interneurons.👍
You are always the best! I shall request a video about concussion. I will greatly appreciate if you could explain what happens to brain tissue, and why such symptoms happens, as you explain with anatomy and physiology of brain.
Great explanation sir❤❤ thankyou
Your videos are very helpful! Thank you!!!
Damn, this is a really well-explained video. Excellent content! Subbed
