Nerve Impulses and Reflexes
Investigate how information travels as electrical impulses along nerve cells and across synapses, and explore the rapid, automatic nature of reflex actions that protect the body from harm.
About This Topic
Investigate how information travels as electrical impulses along nerve cells and across synapses, and explore the rapid, automatic nature of reflex actions that protect the body from harm.
Key Questions
- Explain the pathway of a reflex arc from stimulus to response.
- Analyse a diagram of a synapse to describe how nerve signals are transmitted between neurones.
- Compare a reflex action with a conscious action in terms of speed and control.
