The Peripheral Nervous System (PNS)
The diagram on the right labels the two sections of the CNS. Use a
coloured pen to outline and label the Peripheral Nervous System.
The PNS has two sections: the somatic and the autonomic nervous
systems.

Types of Neurons (nerve cells)
13. How many neurons in a human brain? ______________________________ (1 mark)
14. What is the range of sizes of neurones? _____________________________(1 mark)
15. Neurons have similarities and differences to other types of cells: Complete the table
Similarities to other cells
Differences to other cells
(4 marks)
Neurons are specialized to carry electrochemical messages extremely quickly. Electrochemical
pulses travel along the length of a neuron, then chemicals called neurotransmitters, carry the
message across the gap (called a synapse) to the next neuron to start the electrochemical pulse in it.

Dendrite: ______________________________________________________________________
Axon: ________________________________________________________________________

17. Make a neuron or brain model
Go to: http://faculty.washington.edu/chudler/chmodel.html#string
There are several ideas for making a model neuron or brain.
Choose the model you wish to make. You will need to bring the materials you need (check out
the requirements for each model).
Your model must be completely labelled and you need to take a photo of the final product to
include at the end of this document in your report. (10 marks)
GO to http://faculty.washington.edu/chudler/spinal.html
18. The appearance of the central nervous system is divided into gray matter and white
matter. Find out what parts of the neurons make up the gray matter and white matter and
describe them. Insert an image to show gray and white
matter:
