Nervous System Worksheet – Neurons, Synapses & Action Potentials

This resource introduces students to the structure and function of the nervous system through a series of clear, scaffolded worksheet activities.

Students explore the divisions of the nervous system, the structure of neurons, the roles of neuroglial cells, sensory receptors, action potentials, synapses, and saltatory conduction. The activities are designed to reinforce both biological understanding and correct scientific terminology.

Suitable for KS4 Biology, GCSE, and senior secondary Biology / Human Biology, this resource works well for classwork, revision, homework, or exam preparation.
