Which is greater - The extent of membrane polarization at threshold potential or that of the resting membrane potential?
A cell is more depolarized at it's threshold potential than it is at it's resting potential. This is important because a nervous system where a random excitatory post synaptic potential (epsp) would trigger the next neuron would lead to an overly excitable nervous system (btw, this is why caffeine makes you jittery).
Do all cells have a resting potential of -70mV?
No there is a range of resting potentials. For example retinal ganglion cells have a resting potential of -65 mV while the endocochlear potential is +80 mV.
What is a resting motor neuron expected to do?
exhibit a resting potential that is more negative than the "threshold" potential
A resting motor neuron is expected to?
exhibit a resting potential that is more negative than the "threshold" potential.
What about a cell's resting membrane potential is FALSE?
The resting membrane potential is maintained by solely by passive transport processes.

If a resting potential becomes more negative what happens to the cell?
When the membrane potential becomes more negative it is being hyperpolarized. Remember the resting membrane potential is already at a negative state (~70mV). So if you are making a comparison of a membrane potential that is hyperpolarized in comparison to a resting membrane potential, the resting membrane potential is said to be more depolarized.When the membrane potential becomes more positive it is called depolarization.
What about a cell's resting membrane potential is FALSE?
The resting membrane potential is maintained by solely by passive transport processes.
What is the charge on the inside membrane during the resting membrane potential?
The resting membrane potential of a typical neuron is around -65mV
What is the inside charge of a nerve at its resting potentail?
Neurons have a resting membrane potential of approximately -70mV. Muscle cells have a resting membrane potential of approximately -90mV.
The electrical charge of an inactive neuron is known as?
Potential, ok well we all know it's a potential, but which one? Is it Action Potential, Synaptic Potential or Membrane Potential. Just saying Potential isn't saying much?
When a cell is at rest?
resting potential
What system keeps the neuron at resting potential?
sodium-potential pump
During an action potential hyperpolarization beyond more negative to the resting membrane potential is primarily due to?
Potential hyperpolarization are more negative to the resting membrane potential because of voltage. This is taught in biology.
