[@rebeccam3775]

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

[@MissEstruchBiology]

aww thank you Rebecca! I'm so pleased you are finding the videos helpful. Good luck with your mocks.

[@anaymorjaria6447]

man this took me 2 hours to actually understand

[@Mrh.h4ckz]

At around 6:35 that buzzing noise triggered an action potential in my ears

[@MissEstruchBiology]

Your sound receptors must be more sensitive than mine 😄 I don't hear any buzzing

[@Mrh.h4ckz]

Nahhh I swear down there’s like a high pitched ringing noise I’m deffo not trippin 😂

[@kayceelondon]

@@Mrh.h4ckz lmaoo

[@ranix4866]

I hear it to but its faint lol

[@michaelrivers240703]

its from 6:30 to 11:26, really annoying but these are the only videos I learn from. have to suck it up.

[@totow5300]

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. :)

[@MissEstruchBiology]

Thank you for your lovely comment 😊 Really pleased they are helping you.

[@sophiahxazz8750]

you are by far my favourite teacher and i doubt it will change, thank you for all the videos

[@MissEstruchBiology]

aww thank you so much ☺ You're so welcome and I'm really pleased you like them!!

[@denisabatrinu8831]

Just wanted to let you know how helpful these videos are especially when I struggle to teach myself content missed in lockdown!! Thank you:)

[@MissEstruchBiology]

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 😊

[@bellastarmartin4601]

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 👍

[@MissEstruchBiology]

yes exactly!!! So important to be able to bullet point kept terms for the mark scheme

[@Lavin.]

hi, did we need to know about acetylcholine for the synapses?

[@jukebox2568]

So helpful, thank you!!

[@MissEstruchBiology]

You're welcome 😊

[@tolaniosena]

love this!

[@Masowe.]

this is very heavy, thank you

[@chewcharlie32]

Fantastic !! So helpful....thanks so much 👏👏😊

[@MissEstruchBiology]

You're very welcome ☺ So pleased you liked it.

[@markedexpression3397]

I understood absolutely nothing. I'm so dumb oml so many words 😭😭

[@user-te5ep6em4b]

Real 😓

[@Megan-lc7rf]

how does the neuromusclar junction link to ca2+ ions then in sarcolemma and sliding filament theory?

[@TruthSikher]

Thank you. I'm doing psychology, not biology, but this was very useful still.

[@MissEstruchBiology]

ahh that's so interesting to know this overlaps!

[@TruthSikher]

@@MissEstruchBiology Yeah :) Biopsychology is one of the main topics. Also touches on nervous system, endocrine, the brain and biological rhythms.

[@WarMoose20]

Great video once again, thank you very much!

[@MissEstruchBiology]

☺ thank you so much

[@WarMoose20]

@@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!

[@MissEstruchBiology]

@@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!

[@ummaig9442]

11:52 just wondering why it says membrane potential ‘increases’ to -80mv when it’s decreasing surely as negative ions are moving in ? x

[@hannahsarshar9396]

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?

[@Zen_Zen_Zense]

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)

[@millie6189]

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!

[@MissEstruchBiology]

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.

[@syno894]

@@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?

[@Sara-sc6nm]

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?

[@MissEstruchBiology]

For AQA it should be -70mV. Hyperpolarisation is less than -70mV

[@user-xf4xo3ix6q]

I'm sure I'll be hearing your voice in my head during my exam in a few days😂😬

[@MissEstruchBiology]

😄🤣 Good luck!!

[@sarahibrahmi]

Hi, so just to clarify, neurotransmitters are what is transfered across the synapse and nervous impulses are transmitted across the axons?

[@MissEstruchBiology]

Hi Sarah, Yes, that's exactly it! 😊

[@sarahibrahmi]

@@MissEstruchBiology Thank you 💕
