VERIFIED ANSWERS|ALREADY A+
GRADED|GUARANTEED PASS
The action potential changes the membrane potential from BLANK mV (resting) to BLANK mV
and back again to the resting membrane potential
This results from a change in membrane permeability first to BLANK and then to BLANK, due to
the opening of what type of ion channels? BLANK - -70, +30
Na+, K+, and voltage gated channels
Where is the density of voltage gated Na+ channels the greatest? BLANK
What areas of the neuron generate signals that operate these voltage- gated channels? BLANK -
axon hillock
Dendrites and cell body
If the membrane reaches the trigger point known as BLANK, what electrical potential will be
generated? BLANK
