What are the stages the membrane potential goes through during an action potential? Describe each stage in terms of the changes in sodium and potassium ions inside the cell. Name and describe the two types of refractory periods, and what, if anything would make a neuron fire during a refractory period.

Expert Solution

the image indicates that generally cells have - 70 millivolt charge.

as the signal molecules takes entry the sodium gated channels opens when sodium ions moves inside and the charge of cell becomes - 60. again and again Sodium ions most inside and then leads to depolarization of cell or increase in positive charge. At this. Shall become depolarized with + 20 charge.

we are sodium channels works which allowed entry of sodium ions from outside the cell.

hair Sodium Potassium pump also works which allows entry of 2 potassium ions and pumping of 3 sodium ions outside the cell.

go through the diagram as all the things are mentioned in the diagram.

A flow chart for this: Describe the various stages that a neuron goes through when it receives excitatory neurotransmitters, and when it receives inhibitory neurotransmitters. You should be able to use the following terms accurately in your description: polarized, resting potential, action potential threshold, depolarize, repolarize, hyperpolarize, absolute refractory period, and relative refractory period.
