I just wanted to say how grateful I am for your videos! I’ve been watching all your videos, and they’ve really helped me understand the content for my mocks. I wish I had come across your channel sooner, but it’s better late than never. I’ve recommended you to all my friends, I feel as though the way in which you explain it sounds so simple but still in depth. And I love the fact that the videos are specifically for AQA biology, as in the past, I struggled to find any that were. Thank you so much again! I wish you the best with everything
Haven't had this lesson yet but this is great for making notes.I really like how your broken down the Function of a synapse since you have to be careful not to write too much & hit those key words in the mark scheme 👍
Hi, you said neuromuscular junctions are excitatory because they trigger action potentials but I thought they triggered contraction in muscle? Thank you for great videos!
Hi Millie You are right! They do trigger the muscles to contract and not an action potential as it isn't a neurone! Good spot. It's excitatory because it triggers an event rather than inhibits one.
@@MissEstruchBiology So is a wave of depolarisation in the T tubules of a muscle fibre not the same thing as an action potential? Is a wave of depolarisation only considered an "action potential" is if takes place in a neurone?
@@MissEstruchBiology thanks for all your videos, they've been amazing! Ended up finishing my HE course with 12 distinctions, 3 merits (AAB equiv) and got offers from KCL/Uni of Manchester & Uclan for mental health nursing, and your videos played a real part in dissecting complex biological concepts into easy to understand chunks. Thanks once again Miss E!
@@WarMoose20 Congratulations!!! That is amazing, you must be so pleased! I hope you have a fun and relaxing summer planned. So happy that my content helped you, that means a lot, and thank you for taking the time to write such a lovely comment, that means so much too!
Hi i read in the aqa book that resting potential is at -65mV and i think in the cgp book it was -70mV and hyperpolarisation is -70mV. Can I use either value?
Thank you so much for your videos! One question, when do you put Soduim voltage gated ion channels, and when is it Sodium ion channels? Is there a difference?
There is a difference, but all you need to know is that the ones Miss Estruch is referring to are the voltage ones. After all the voltage ones prevent Na+ from entering, this will make sure there isn't a constant action potential, the only time an action protentional is needed is when an impulse passes (the voltage)

aww thank you Rebecca! I'm so pleased you are finding the videos helpful.
Good luck with your mocks.
you are by far my favourite teacher and i doubt it will change, thank you for all the videos
aww thank you so much ☺ You're so welcome and I'm really pleased you like them!!
At around 6:35 that buzzing noise triggered an action potential in my ears
Your sound receptors must be more sensitive than mine 😄 I don't hear any buzzing
Nahhh I swear down there’s like a high pitched ringing noise I’m deffo not trippin 😂
@@Mrh.h4ckz lmaoo
I hear it to but its faint lol
its from 6:30 to 11:26, really annoying but these are the only videos I learn from. have to suck it up.
man this took me 2 hours to actually understand
Thank you so much for all your videos, they've helped me so much! Really appreciate all your hard work that's gone in to making them all. :)
Thank you for your lovely comment 😊 Really pleased they are helping you.
Just wanted to let you know how helpful these videos are especially when I struggle to teach myself content missed in lockdown!! Thank you:)
It must be so hard with all the disruption and home learning, really glad that these are helping in some way! Good luck with your studies 😊

yes exactly!!! So important to be able to bullet point kept terms for the mark scheme
Thank you. I'm doing psychology, not biology, but this was very useful still.
ahh that's so interesting to know this overlaps!
@@MissEstruchBiology Yeah :) Biopsychology is one of the main topics. Also touches on nervous system, endocrine, the brain and biological rhythms.
I understood absolutely nothing. I'm so dumb oml so many words 😭😭
Real 😓
So helpful, thank you!!
You're welcome 😊

love this!
Fantastic !! So helpful....thanks so much 👏👏😊
You're very welcome ☺ So pleased you liked it.
hi, did we need to know about acetylcholine for the synapses?
this is very heavy, thank you
I'm sure I'll be hearing your voice in my head during my exam in a few days😂😬
😄🤣 Good luck!!
If the enzyme is not working what happens?
11:52 just wondering why it says membrane potential ‘increases’ to -80mv when it’s decreasing surely as negative ions are moving in ? x
Great video once again, thank you very much!
☺ thank you so much

how does the neuromusclar junction link to ca2+ ions then in sarcolemma and sliding filament theory?
Hi i read in the aqa book that resting potential is at -65mV and i think in the cgp book it was -70mV and hyperpolarisation is -70mV. Can I use either value?
For AQA it should be -70mV. Hyperpolarisation is less than -70mV
phew another part covered

Hi, so just to clarify, neurotransmitters are what is transfered across the synapse and nervous impulses are transmitted across the axons?
Hi Sarah,
Yes, that's exactly it! 😊
@@MissEstruchBiology Thank you 💕

Who’s here doing last min revision
Good luck 🤞🤞
