Membrane Potential
*BLANK* is the primary ion that determines the resting membrane potential
What is K+
During the relative refractory period, a *BLANK* than normal graded potential is required to trigger an action potential
What is higher
When ions are transported across the cell membrane, it creates a *BLANK* gradient
What is electrical gradient
Action potentials are uniform, *BLANK or BLANK* depolarizations that can travel over long distances
What is all or nothing
The electrical gradient between the extracellular fluid and the intracellular fluid is know as the *BLANK BLANK* potential difference
What is resting membrane...
The *BLANK* refractory period is when a second action potential cannot be triggered
What is absolute refractory period
The movement of an ion across the cell membrane is influenced by the *BLANK BLANK* for that ion
What is electrochemical gradient
The rising phase of the action potential is due to increased *BLANK* permeability, the falling phase of the action potential is due to increased *BLANK* permeability
What is Na+ and K+
The membrane potential that exactly opposes the concentration gradient of an ion is know as the *BLANK BLANK*.
What is equilibrium potential
When action potentials jump from node of Ranvier to node of Ranvier it is called *BLANK BLANK*
What is saltatory conduction
