Transmit
information
from
sensory
receptors
View source

Passes
information
to
subsequent
neuron

Leads to
action potential
View source
What are the steps leading to an action potential?
Graded/local potentials
occur
Threshold
reached,
influx of Sodium
Action potential reached,
potassium
pumped out
Refractory period
ensures uni-directional movement
Resting potential
re-established
