What substances plays a mojor role in generating the membrane potential of a neuron?
Well, for starters, membrane potential is a separation of charges across the membrane. So i think what you mean is "generating the action potential in a neuron". So in that case The substance that plays a major role in generating an action potential is Sodium (Na+). However, if you really mean membrane potential, there is only two substances associated with that and those are sodium (Na+) and potassium (K+).However, in truth, the generation of an action potential depends on the ligand and its receptor.
What parts of a neuron is capable of generating a graded potential?
The dendrites portion of a neuron will generate a potential.
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.

The dendrites portion of a neuron will generate a potential.
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 changes occur in the neuron during an action potential?
During an action potential, the neuron undergoes a rapid change in membrane potential as sodium ions rush into the cell, leading to depolarization. Subsequently, potassium ions move out of the cell, repolarizing the membrane back to its resting state. This rapid change in membrane potential allows for the transmission of electrical signals along the neuron.
What is the small change in the charge across a neuron's membrane called?
Action Potential
