In this video, Dr Mike explains that excitable tissues like muscles and neurons require a resting membrane potential in order to contract or send signals.
This was actually super concise, spot on, right to the point. Easy to understand. No useless cartoons to illustrate points, and enthusiasm added to the core understanding for me. Thanks.
You are an amazing teacher! I learn more from your videos than from the very boring long lectures filled with certain concepts that we don’t need. You are precise, straight to the point and your videos are short and efficient, no time wasted. Thank you!
My Biology teacher says that I don't pay attention, little did she know that her lectures are not good and Thanks to Dr. Mike for getting me on track and making the concepts clear and concise
I've been going over and over notes and a lot of other youtube videos and remained completely lost until your video. Thank you for making this easy to understand!
Love the accent.That was the best explanation Ive ever heard. My class just throws pargraphs upon paragraphs at me and more wirds but with your picture and clear explanation I grasped it. Thank you so much!!!
Thank you million times Dr. You and two other genius in the youtube helped me a lot to score 95 marks for the exam. Im readying for the finals now.Really grateful 🥺❤️. I never attend a lecture. Purely the text books and these videos of you people.❤❤
Thank you so much. I have my anatomy exam today and I was so so confused on potassium and sodium pumps, and what they did and how the resting membrane potential was formed. Now I understand. It’s so much better!!!
I have no clue of all this stuff but did understand most of it (of course subtracted Dunnig-Krueger effect) So this was at least for me an excellent teaching! ❤ thank you
i am enjoying your videos they have helped me a lot on my school work , i recommended you to my friends and they all agree you are indeed a good teacher. thanks a lot. keep the videos coming
You really are a very gifted teacher indeed! Great clarity and sequencing. So it seems that wherever there are gradients in the universe change can happen...So nerve and muscle cells use up small amounts of energy by hydrolysing ATP to get ready for action when it is needed?...So perhaps gradients should be given more prominence in biology? Even a section dedicated to them? Just a thought. Thank you!!
Hi doctor mike! I've been watching your videos and they're of big help. However, I think the audio is too low that makes it quite hard to decipher the words spoken from the video.
Do nonexcitable cells have a resting membrane potential? In the video you said that only excitable cells have a rmp, but I thought that all cells had it. Could someone clear that up for me XD
Potassium ions are linked with large proteins. The proteins are negatively charged. So when potassium ions escapes the cell, proteins can't escape the cell due to their large size. The bond between the two is still there. It's a chemical bond. It can't be broken just by a simple diffusion of potassium ions out of the cell. So the proteins remain stuck on the inside of the membrane. While k+ ions remain stuck on the outside of membrane in ecf. Therefore the negatively charged proteins stuck to the membrane inside causes a NEGATIVE potential inside. Hope that explains... 😊
On the outside of the membrane. Bcoz it's the potential of the membrane. That's why when a stimulus is received, polarity is changed at that particular point of cell membrane.

His muscles, biceps, arms, and back all distracted me in this video. Lol. Who else is with me? Great video and explanation!
😂😂😂
For real
Right
Me too
Great video coz of the guy in it😂
This man is so professional he didnt even flinch or falter after dropping the marker at 3:40

i agree!
Taught me more in 5 mins than a 2 hr lecture
Exactly
This is so trueee
i came here after watching 3 videos and now i finally understand everything after watching this. Thank you!!
Which videos are those.. would you mind sharing them
My Biology teacher says that I don't pay attention, little did she know that her lectures are not good and Thanks to Dr. Mike for getting me on track and making the concepts clear and concise
I am doing Physiological Sciences and you are my Best Teacher. 🙂

SO helpful! Makes it so much easier to understand!!
These 5 minutes saves 1 hr lecture and I was just confused regarding my book diagram but after watching this my all confusions are cleared. Thanks ❤❤
This is one of the most clarifying videos on this topic I've seen in a while!
Not one person would ever hit "dislike" on Dr. Mike's videos. I've never seen science explained more clearly.
Thank you million times Dr. You and two other genius in the youtube helped me a lot to score 95 marks for the exam. Im readying for the finals now.Really grateful 🥺❤️. I never attend a lecture. Purely the text books and these videos of you people.❤❤
You are honestly the best teacher ever
This topic has been better explained than Armando Hasundungan. Very nice, short and simple. 😀
Awesome videos! Studying Biology in undergrad right now and your videos are a great supplement and help summarize important concepts. Thanks so much
That's wonderful! Let me know if there are any videos you think I should record!
Best of luck with your study!
Thank you so much. I have my anatomy exam today and I was so so confused on potassium and sodium pumps, and what they did and how the resting membrane potential was formed. Now I understand. It’s so much better!!!
Bro your explanation are straight to the point,,,short videos making me watch move,,,may God bless your channel ☺️☺️☺️
I have to hand it to you. You are saving me in Physiology
Such an amazing teacher
I get to understand everything when I watch his videos
Keep it up
I was waiting for you the whole video to pick the marker up
Perfectly clear, you are an amazing teacher. Lucky I found you on my first semester on med school now life would be much better
Thanks Dr .that’s very clear I read my lecture for many times ( biomedical physiology ) and it’s really complicated , your explanation was clever
you don't need to ask for a sub, your video said it all!! superb presentation!
Thank you for putting things so clearly! So helpful for a visual learner like me!
You are just amazing, you made anatomy very simple. Very importantly, you teach with understanding
dr mike u save my life everyday
I wish I was as built and smart as this guy!
I have no clue of all this stuff but did understand most of it (of course subtracted Dunnig-Krueger effect)
So this was at least for me an excellent teaching! ❤ thank you
wow this really helped me! i learned a lot more then i would understand in one lecture!
Beautiful, understandable explanation, thank you.
Thank you so much Dr Mike, your videos really helped me. I used your brilliant ideas in my assignments. God Bless you, Thanks a lot .
i am enjoying your videos they have helped me a lot on my school work , i recommended you to my friends and they all agree you are indeed a good teacher. thanks a lot. keep the videos coming
This really helped me on my bio final tysm.
so so easy to understand helping me through psychobiology so much!!
This was so amazingly clear, thank you so much!
You are always soooo precise....I really get your lectures... thanks
This is the best video made for rmp thank you :)
nah

عمي شهلشرح الراقي
thank u so much Dr
thank you! this helped a bunch for understanding!!!
thank you
So simple .. thank you
Amazing teacher!
thank you!
Amazing!!
I always understand easily from your tutorials but Kindly work on the visual quality. Sometimes things ain't too visible 😊
Another great video! Thank you!!
Enlightening little clip!!
Thank you that was very clear
Thanks a lot really
The time is took to draw that phospholipid bilayer!😂

3:39 RIP whiteboard marker
How to like this video twenty times???❤️
I love you.
Thanksssss
Do nonexcitable cells have a resting membrane potential? In the video you said that only excitable cells have a rmp, but I thought that all cells had it. Could someone clear that up for me XD
Excellent question. I hope Dr. Mike sees this...well it is over a year since you asked.
HANDSOME !!

Thanksss
But why for instance the charge inside is +30q,and outside the charge is +60q. Charge inside is just smaller,but why is it negative?
Look, outside charge is more positive than inside so it is considered as negative in comparison to the outside charge.
Potassium ions are linked with large proteins. The proteins are negatively charged.
So when potassium ions escapes the cell, proteins can't escape the cell due to their large size. The bond between the two is still there. It's a chemical bond. It can't be broken just by a simple diffusion of potassium ions out of the cell.
So the proteins remain stuck on the inside of the membrane. While k+ ions remain stuck on the outside of membrane in ecf.
Therefore the negatively charged proteins stuck to the membrane inside causes a NEGATIVE potential inside.
Hope that explains... 😊
"These excitable tissues just like me" 😂🤞🏽
Why doesn’t the influx of K+ from the pump counteract the outward flow of K+?
Would the leak channels basically cuase the RMP to change? Therefore it produces a graded potential right?
does the resting membrane potential exist across the neuron (from the soma to the terminal)?
@SarahChicharro The ring on his finger should snap you right back from your distraction :)
Him: Focus
Me: I'm fo..(seeing his muscles)
Who's dr.matt and dr.mike ??
If its negative 70mv in cell does that mean is it positive 70mv outside the cell?
On the outside of the membrane. Bcoz it's the potential of the membrane. That's why when a stimulus is received, polarity is changed at that particular point of cell membrane.
GOD DAMN.
👍🏻👍🏻
OKAY YOU’RE HOT I CAN’T FOCUS LOL 😂😭
You can be large and in charge my neurotransmitters
I hope you put Arabic translate
69th comment nicee...also great video really helped me.
I don't see where the negative stuff comes from.
