The Nervous System: Action Potentials | A Level Biology Revision

[@paarthivisavalia4862]

- straight to the point
- relates to the marksheme
- clear explanations and definitions
Love it! Really helping me teach myself A-Level content :))

[@tailoredtutors]

That's amazing. Thanks for watching!

[@mile3687]

Thank you so much for the videos, better than alot of the videos out there. Specifically target marking scheme and examination technique. 10/10. Hope you make full chapter videos soon.

[@aliceg2886]

Using this to help me with my psychology degree! Thank you!!

[@tailoredtutors]

That's amazing, I'm so glad to hear that Alice! :D

[@oceantamara5439]

Thank you so much for this channel!! It has helped me so much especially now with AQA going linear! :)

[@naanaesi]

you're a fabulous teacher

[@tailoredtutors]

Thank YOU! 😍

[@sherineahmed1328]

i really do need a synapse & Striated muscle A2 biology video just like this one

[@TariroDhauro]

well explained

[@rahi5844]

Thank you! this was so helpful :)

[@bossmankarwa]

What causes the initial sodium channels to open (before positive feedback starts to occur). Is it the energy from the stimulus? You talk about it in #3 - 'Threshold'.

[@hoyama1520]

very help. thanks!

[@tailoredtutors]

Glad it helped!

Impressive

[@avfczone]

Brill cheers mate 👍🏻

[@tailoredtutors]

You're very welcome! You can always find more free videos on our website!

[@officialexclusive936]

Plz make a videon on transmission of action potential also

[@Kudakwashe.Chikonyora]

thanks so much

[@Relaxingsongs-qo7kr]

I have no idea what's going on this is o confusing. Can you do a condensed video on this topic

[@layanjabr436]

Are the potassium ion channels opened during depolarisation ?

[@khalil7011]

No, Na+ ions diffuse rapidly into the axon via facilitated diffusion to reverse the resting potential, No K+ though

[@manavdivecha2097]

thanks :D

[@tailoredtutors]

Happy to help :)

[@theshadeofjett]

so after hyperpolarisation a nerve impulse is released?

[@taqdeesrehman9812]

Hyperpolarisation is when the membrane can't depolase. This is caused by overshoot which occurs due to the outward flow of potassium ions reaching equillibrium.
