I genuinely appreciate how clear and engaging your videos are! A huge thanks for making complex topics so accessible and fun. Your help has been invaluable!
Preparing for an exam and I watched about 5 videos on this theory before finding yours! Absolutely love the clear precise way you explain things, draw the pictures as you go, and then recap at the end. So much gratitude to you and you have a new follower. Adding the clips of your family makes it all the better. Thanks again!
THANKS a BUNCH!!! Halfway through A&P 1, for second time in 28yrs...yep, returned to college for LPN to RN, BSN and need to repeat the sciences, due to age of them. You really break things down nicely, and clarify what the online textbooks do not!
Your videos and illustrations are absolutely incredible. You explain things where it’s easy to understand, and your illustrations are clear, colorful and beautiful.You make Anatomy enjoyable! I am a fan!!!!
Thank you!!!! Really your videos have been making things alot easier for me for the past 2 years ! Thanks alot for making complex topics clearer than ever!!
You are wonderful!!! You can make hard subjects super easy to learn. I truly appreciate all your videos. Thank you so so much for being such a talented teacher! PS You're funny! You definitely can do sit-down comedy.
Wow!! You made this chapter super easy!! Your art skill made it all!! Actually your explaning skill did most of them haha. What an awesome lecture!! I am so lucky to watch your lecture. Thanks again!!
Thank you! This was great. I’ve watched several videos & most of them went too fast. This was at a great pace & thorough. It really helped!!! Thank you for your clearly explaining complex topic.
You were the best like all the timme but a little bet in a hurry. The speed of teaching was somewhat faster. But it was 100 times better than what other teachers explain.
Whenever the calcium ions binded with the troponin which pulls back the tropomyosin so that binding sites are exposed and myosin heads will be able to form a connection with them
I had Guillain-Barré and was left with weakness in my quads. How many neuro transmitters are there that stimulate a particular muscle? hundreds,thousands,millions? And perhaps mine didn’t all return?
Each muscle will have somewhere in the hundreds of thousands of muscles fibers, and each fiber has one motor neuron terminal connected to it. The neurotransmitters are the tiny chemicals released from the axon terminal to the muscle fibers...not sure how many of those there are, but it's a lot!
Actually not true that the signal must come from the brain. Electrical stimulation can come from anywhere and in biological systems, it may come through short-circuiting via interneurons. What can happen is in response to a stimulus, such as something touching a hot stove, polysynaptic reflex arc, sensory information from nociceptors activates interneurons in the spinal cord. The interneuron transmits the signal to a motor neuron, short-circuiting transmission to the brain.

Had to complete an assignment for my human physiology class based of this video lol great work!
Haha, thanks! Hope the assignment went well!
@@SiebertScience😂❤
This is the easily clearest and best video I have come across on this subject.
Thank you so much!
You, sir, are THE best at explaining all of these very confusing concepts, I appreciate your drawing and explanations more than I can say. THANK YOU!
I've watched tons of videos, read tons of blogs, but this is the first time I really get it. This is awesome, thank you!

This helped so much as we are to know 22-23 steps to write from excitation to cross bridge and finish with reset. Very clear, thank you.
Wow the baby is so pretty and smart too learning the "Filament" 🥰
Thank you so much for this!!! I’m studying for the MCAT and this really helped me understand muscle contraction!!
You’re welcome! Good luck on the MCAT!
liked the visuals and how simple this was explained, thanks
Incredibly helpful!
You are AWESOME!!! And I love your drawings!!!! Thank you!
Oh, thank you! Glad you like the drawings...they take a while :)
Thank you so much. These are very helpful for online students. Seeing it helps better than reading.
i never have commented on a youtube video but this one rocks. was just looking for a thorough review, this was great. thanks !
Awesome!! 😊.. I'm so happy to find all these videos..God bless you and your family..
Gonna recommend ur channel to my friends. Everything has been taught so clearly.
Thanks for sharing and your daughter is so smart 😍🥰
Wow!! You made this chapter super easy!! Your art skill made it all!! Actually your explaning skill did most of them haha.
What an awesome lecture!! I am so lucky to watch your lecture. Thanks again!!
this really helped me for my anatomy class, thank you!!!
Thank you!! This was the best video to understand this topic. I was having trouble visualizing this concept and now it all makes sense!!!
Awesome! Glad it was helpful. Also, my daughter's name is Alondra!
@@SiebertScience no way! That’s actually really cool. I don’t meet a lot of people named Alondra. It’s a beautiful name :)
I'm having my exams tomorrow on this topic and this video has helped me understand. Thank you
THANK YOU for all the free resources u provide I've been a fan since 3 years ago!
Thank you very much Professor for your easy and clear explanation. I love all your videos!!
this guy is great 😃👍
im stressing over anatomy and physiology, but he makes it easy to understand. thanks for making this awesome video!
Thank you! This was great. I’ve watched several videos & most of them went too fast. This was at a great pace & thorough. It really helped!!! Thank you for your clearly explaining complex topic.
You've really developed my understanding. Thank you.
You really explain this concept well!❤
thank u seriously, there is an anatomy exam coming in a few days and this video helped me a lot to understand more about what happens in the muscles
Hope the exam went well!
You are an awesome teacher, love that little babi!
Wow you explained it in a really easy way ❤❤
This is such a great explanation. Thank you!

I think I'm learning more from you than my lecturer
so helpful!! thank you!!
Thank you for the effort ❤
Well explained thank you🎉🎉
Thank you so much for your great explanation, it's clearly answer my wondering about muscle contraction 🙏
Hey wait in my book it says thick filaments are purple 4:41 which is correct?😅
sankyu for the video!
This was great 😮💨
Where do magnesium and potassium ions come into play in muscle contraction and relaxation?
Whenever the calcium ions binded with the troponin which pulls back the tropomyosin so that binding sites are exposed and myosin heads will be able to form a connection with them
thank you for this!!
Thank you doctor
very helpful thank u!
God bless you.
thank you for sharing the video
THANK YOU!!!
oh Thank God! I found this!
Thank you so much
Thanks for sharing. It's a great video.
You're welcome! Thanks for the comment.
I owe you my life
Go do a nice deed for someone else, and I'll consider the debt paid. ;)
THANK YOU
but there is atp needed for contraction how come you say there isnt
You're really good
Thanks
Thanks 👍👍👍👍👍❤❤❤❤

Too fast
Speak way too fast!
Sorry! I think you can adjust the playback speed of RUclips videos. Maybe slowing the video down could help?
Guy is wrong. You do not speak too fast. Volume is good too.
Not exactly. Close though.
