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

6. Three types of Nerve Cells
Sensory Neurons
Inter Neurons
Motor Neurons

9. In a synapse vesicles release neurotransmitters which cause the next neuron to fire.
