Responses - receptors, neurones, nerve impulses and muscle contraction playlist

Neurone structures, how action potentials work and how muscles contract

This playlist includes videos on the following:

Receptors – Pacinian corpuscles and Rods & cones: how they work

Neurone structure - sensory, relay/intermediate and motor

Resting potential - how it is maintained

Action potentials - how they occur, their conductance and factors affecting the speed of conductance

Synapses - structure, function and modulation

Synapses vs NMJs

Brain and Nervous system structure & function and Reflex actions.

Taxes & kineses - the directional and non-directional responses of simple organisms

Muscle contraction - the process and how to remember it!

Control of the Heart Rate - including autonomic/somatic, sympathetic/parasympathetic and how heart rate is regulated by the nervous system.

Energy for muscle contraction; Slow and fast twitch fibres - how aerobic, anaerobic and phosphocreatine systems work with their advantages and disadvantages. How slow and fast twitch fibres work, with their advantages and disadvantages.

Structure and function of the 3 muscle types - skeletal, smooth and cardiac (not required for AQA)

I managed to achieve an A in biology! I couldn’t believe it, especially after being told in year 12 I wouldn’t get above a D! Your website completely changed my grades and helped me get consistent As in my assessments and exams throughout year 13. Keep doing what you are doing, because I wouldn’t be where I am now without your work! 😊

Your Teacher


I'm a qualified biology teacher and online tutor who makes videos on A level biology topics which are clear in their explanations, straightforward in their format and mark-earning in their exam question hints.

I LOVE my subject! But I also know that many A level students want to 'know what they need to know' and need help to unlock the marks in the exams, so I have formatted my videos to be straightforward, clear and pacy. They may not be 'beautiful' (I am no techy!) but the content is high quality.

Frequently Asked Questions

Can I share or copy these materials?
No. All materials are copyright biologycarol. These are for YOUR personal use only and must not be shared or copied. The charge I make for these videos is the only way I can carry on making and improving them. Please help me keep going. I can assure you this is not making me rich 😬! If inconsistencies in IP address data and other evidence of unusual activity is noticed, I reserve the right to cancel your subscription.
How long do I have access to the course?
For a calendar year from the date of subscription. Even If this runs past the end of the academic year this is still very good value (far cheaper than private tuition!).
What If I don't need to subscribe for a full 12 months?
Sadly, only subscriptions for a full calendar year are possible - I cannot get subscriptions to end at the end of summer🙁. I am confident that the quality of the content makes your subscription good value for money, even if you might stop using them before your subscription runs out.
How do I stop recurring subscriptions? I only need this for a year!
Easily sorted! As soon as you have received the email confirming your purchase, log back into biologycarol and click on your picture in top right of the header. Click on Manage subscriptions > Cancel.
What if I'm unhappy with the course?
If you have any doubts check out my YouTube channel ( ) where you can see a few examples of my videos. As this is digital service, sorry but I am unable to offer refunds. Although my intention is to offer accurate and complete content, I do not guarantee to cover all details of any syllabus and I cannot guarantee that errors or omissions have not been made.
What if I have a technical problem?
Please check the Troubleshooter Guides using the link in the footer. If that advice fails, let me know at [email protected]

Seeing as you've decided to invest this much in my tuition, can I just check it doesn't make sense for you to buy one of my Playlist Bundles instead?

The Year 1 (AS) Playlist Bundle gives you ALL the videos that cover the first year of the course for AQA and OCR A for £50 for a year's subscription (full price). These will cover the main AS content, at least, for every exam board.

The Year 1 & Year 2 Playlist Bundle gives you ALL the videos that cover the content for the whole of the AQA and OCR A courses for £100 for a year's subscription (full price). These will cover the majority of the content for any other exam board.

Both of these bundles are ridiculous value for money 😁, being equivalent to 1 or 2 hours of private tuition...
