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 causes the vesicles inside a neuron to fuse with the plasma membrane?
An action potential in the neuron
The start of an action potential?
An action potential starts when sodium channels in a neuron end open and sodium ions rush is, depolarizing the neuron's membrane.
What is membrane polarity?
-70 mV this potential difference in a resting neuron (Vr) is called the resting membrane potential, and the membrane is said to be polarized.
What substances plays the major role in generating the membrane potential of a neuron?
sodium
It is the membrane potential of a neuron at rest?
Yes,the membrane potential of a neuron is at rest because it is the difference in electrical charge between inside and outside a resting neuron.
The resting membrane potential of a neuron is about?
-70mV
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 causes the vesicles inside a neuron to fuse with the plasma membrane?
An action potential in the neuron
What is the rapid change in membrane's potential caused by the deplariztion of a neuron?
action potential
_____ is the process by which the neuron regains its negative resting membrane potential?
Repolarization
The start of an action potential?
An action potential starts when sodium channels in a neuron end open and sodium ions rush is, depolarizing the neuron's membrane.
What is membrane polarity?
-70 mV this potential difference in a resting neuron (Vr) is called the resting membrane potential, and the membrane is said to be polarized.
What substances plays the major role in generating the membrane potential of a neuron?
sodium
What is the small change in the charge across a neuron's membrane called?
Action Potential
Through the membrane of a resting neuron highly permeable to potassium ions its membrane potential does not exactly match the equilibrium potential for potassium because the neuronal membrane is?
Slightly permeable to sodium ions.
A neuron fires only when its membrane reaches what?
When it reaches the nerve impulse threshold, the next neuron will fire..
