Lesson details
Key learning points
- Neurones are specialised cells that transmit nerve impulses
- The common structures of neurones, including cell body and axon
- A myelin sheath on some neurones increases the speed of the nerve impulse
- Nerve impulses pass from one neurone to another across a gap called a synapse
- An impulse arriving at a synapse releases neurotransmitters that diffuse across the gap to receptors on the next neurone
Keywords
Neurone - A nerve cell which transmits electrical impulses between different parts of the body.
Axon - The part of a neurone which carries the signal.
Myelin sheath - A fatty coating on the neurone which insulates it.
Synapse - The junction between two neurones.
Neurotransmitter - A chemical transmitter which crosses the synapse and triggers the onward response.
Common misconception
There is usually a lot of confusion over the synapse and how the signal moves from electrical, to chemical, to electrical again. There are many new key words involved, which makes it even harder.
The synapse has been broken down into several stages with clear diagrams and carefully used key words. There are plenty of opportunities to practise using the terminology and explaining the process, including applying it to a real-world scenario.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
