Explore free A-level Biology revision articles about nervous communication, including receptors, neurones, resting potential, action potentials, the transmission of nerve impulses and synapses. These explanations can support students studying AQA, OCR A or Edexcel Salters–Nuffield Biology, although the precise content required varies between exam boards.
Nervous communication revision articles
- Receptors – Nervous Communication Ep 1
Today we are beginning a new series about nervous communication (the type that happens in animals, not making a speech in front of the class)…. Continue Reading → - Neurones and Resting Potential – Nervous Communication Ep 2
The nervous system communicates information by propagating nerve impulses. In the last article we saw how impulses are generated at receptors in response to a… Continue Reading → - Action Potential – Nervous Communication Ep 3
In the last article we learnt that neurone cell-surface membranes are polarised at rest (when they are not being stimulated). However, when a stimulus is… Continue Reading → - Wave of Depolarisation and Speed of Conductance – Nervous Communication Ep 4
Last time we looked at an action potential happening across a neurone cell-surface membrane. The membrane was depolarised and repolarised. However, that depolarisation must be… Continue Reading → - Synapses – Nervous Communication Ep 5
We know that nerve impulses are transmitted along neurones in a wave of depolarisation. But how does a nerve impulse get transmitted from one neurone… Continue Reading →
