No, neurotransmitters that depress the resting potential are called inhibitory neurotransmitters. Excitatory neurotransmitters have the opposite effect, causing depolarization and increasing the likelihood of an action potential.

Explain why the EPSP is larger if the membrane potential becomes more hyperpolarized than the resting membrane potential?

An excitatory postsynaptic potential (EPSP) is larger when the membrane potential is more hyperpolarized than resting potential because the driving force for sodium ions (Na⁺) influx increases. When the membrane is hyperpolarized, the difference between the resting potential and the sodium equilibrium potential is greater, leading to a stronger current flow when sodium channels open. This enhanced influx of sodium ions results in a more significant depolarization, producing a larger EPSP. Essentially, the larger potential difference allows for a greater excitatory response.


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).


What is a resting motor neuron expected to do?

exhibit a resting potential that is more negative than the "threshold" potential


Do all cells have a resting potential of -70mV?

No, not all cells have a resting potential of -70mV. The resting potential of a cell can vary depending on the type of cell and its function. However, many excitable cells, such as neurons, have a resting potential close to -70mV.


A resting motor neuron is expected to?

exhibit a resting potential that is more negative than the "threshold" potential.

What is the relationship between membrane potential and resting potential in a cell?

The resting potential of a cell is the membrane potential when the cell is at rest, typically around -70 millivolts. Membrane potential refers to the difference in electrical charge across the cell membrane. Resting potential is a type of membrane potential that is maintained when the cell is not actively sending signals.

A change in the resting potential of a dendrite from -70 mV to -72 mZV is called what?

A change in the resting potential of a dendrite from -70 mV to -72 mV is called hyperpolarization. Hyperpolarization is when the membrane potential becomes more negative than the resting potential.


When a neuron's resting potential is occurring the neuron is what charge on the inside?

A pencil resting on a desk is an example of what kind of energy?

The pencil resting on a desk has potential energy due to its position in the gravitational field.


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.


Is the resting potential of a neuron approximately -70 microvolts?

Yes, the resting potential of a neuron is typically around -70 millivolts (mV), not microvolts. The resting potential is the membrane potential of a neuron when it is not being stimulated to send a signal.
