1 The Human Nervous System 35-1
Name the three parts of a neuron. Describe the way in which a nerve impulse occurs.

3 Can you label a neuron? Cell body Nucleus - Schwann cell Nucleus
Dendrites Axon Node of Ranvier Nucleus - Schwann cell Schwann cell Myelin sheath Synaptic knob Terminal Branches

4 A faster impulse – the action potential jumps from gap to gap.
Myelin Sheath
