The Nervous System and Hormones
A free video lesson on how the body controls itself — the fast, electrical nervous system and the slower, chemical hormonal system — plus reflexes and homeostasis. Followed by real quiz questions, marked instantly. No account needed.
How does your body react in a flash, yet also control things steadily over hours? This lesson explains the nervous system and reflexes, the hormonal system (insulin, adrenaline and more), how the two compare, and homeostasis — keeping conditions like blood sugar steady. It is part of Learning Hub, a UK-curriculum learning site built by a home-educating family.

Questions parents ask
- What is the difference between the nervous and hormonal systems?
- The nervous system uses fast electrical signals along neurones — great for quick reactions. The hormonal system uses chemical messengers (hormones) carried in the blood — slower to act, but longer-lasting. Together they keep the body coordinated.
- What is a reflex?
- A reflex is a fast, automatic, protective response — like pulling your hand off something hot. It takes a short cut through the spinal cord (via a relay neurone) rather than waiting for the brain, which is what makes it so quick.
- Is this suitable for KS3 and GCSE?
- Yes. Coordination and control is a core biology topic for Years 9 to 11 (KS3 and GCSE), and this lesson and quiz work as a clear introduction.
- Is it really free?
- The video and these questions are free with no account. The full site is £6.99 a month for the whole family, with a 14-day free trial and no card needed to start.
