1
Q
What does the form of the cells of the nervous system suggest?
A
their function
2
Q
What are the cells of the nervous system specialised for?
A
transmission of electrical signals
3
Q
What is the role of ion transporters?
A
move ions against concentration gradient (electrogenic)
4
Q
What is the role of ion channels?
A
allow ions to diffuse down concentration gradient
5
Q
What is the key to using potential to create nerve impulses?
