What’s a neuron? Basic structure:

• Dendrite

• Cell body

• Axon

it’s your turn!

Go to 2.1.3 > Basic Neuron Design > Step 1

• Define the major parts listed in step 1 (under laboratory notebook)

neuron forms

There are 3 major types of neurons.

• Motor neurons

• Sensory neurons

• Interneurons

Model a Neuron

• Use any materials you'd like to create a model of a neuron.
• You should include all structures listed below

• Attach the model to a piece of cardstock paper.
• Label each structure on the paper
• Cell body (soma)
• nucleus
• dendrites
• axon
• myelin sheath
• nodes of Ranvier
• axon terminals
• neurotransmitters
