The Nervous System 1 Flashcards
1
Q
What allows for saltatory conduction?
A
The myelination of nerve fibres
2
Q
How is resting potential generated?
A
Neurons pump sodium and potassium ions across their membranes
3
Q
What is action potential?
A
depolarization and repolarization of the neuron
4
Q
What are nerve impulses?
A
action potentials propagated along the axons of neurons, only initiated if th threshold potential is reached
5
Q
What are synapses?
A
junctions between neurons and between neurons and receptor or effector cells
