Question 1.
What are the three main parts of a neuron?
Show hintHide hint
Think about the structure of a neuron.
Question 2.
What is the role of dendrites?
Show hintHide hint
Consider them as 'receivers' of information.
3Question 3.
What is the primary function of dendrites?
- A) Transmit impulses away from the cell
- B) Receive signals from other neurons
- C) Maintain resting potential
Show hintHide hint
Consider them as the 'antennae' of the neuron.

- True
- False
Show hintHide hint
Recall the phrase 'Myelin is Mighty.'
Question 5.
Explain how both myelination and the nodes of Ranvier affect the speed of impulse conduction in neurons.
Show hintHide hint
Consider how electrical signals flow and what factors can speed up that flow.
Question 6.
Compare and contrast the mechanisms of action potential generation in myelinated versus unmyelinated axons.
Show hintHide hint
Think about the pathways taken by signals in each type of axon.
