A Catalyst article which explores how the nervous system works. Sensitivity, the ability to respond to stimulation, is a product of nervous system activity. How nerve impulses pass around the body, and why these responses are so fast are investigated in the article. Neurones, reflexes, synapses and receptors are also looked at.

This article is from Catalyst: GCSE Science Review 2004, Volume 14, Issue 4.
