The answer that best describes the relative refractory period in the neuron is The resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.
The refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. Thus, because Na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.

What is the difference between plasma membrane and cell membrane?
garri49 [273]
The plasma membrane is the boundary between the cell and its environment. It regulates what enters and exits the cell. Cells must maintain an appropriate amount of molecules to function inside them. They must also have a way to keep things out or to allow things to enter. This is the job of the plasma membrane. The plasma membrane is like the guard at a gated community. The guard must inspect those who enter and those who leave to make sure that only the people and things needed in the community are there.

The cell membrane is a thin semi-permeable membrane that surrounds the cytoplasm of a cell. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell, while keeping other substances out. It also serves as a base of attachment for the cytoskeleton in some organisms and the cell wall in others. Thus the cell membrane also serves to help support the cell and help maintain its shape.

Explanation:

The human excretory system consists of   : Kidney ,ureter ,urinary bladder and urethra .The figure is shown below .

Now , as far as functions are concerned we have :

Kidneys : They have excretory units called nephrons that  further  consist of :

  • Bowman's capsule
  • PCT (Proximal convoluted tubule )
  • DCT (Distal convoluted tubule)
  • CT (collecting tubule )

In nephrons urine is formed and via ureter it is transported to a hollow sac like structure called  urinary bladder .

This bladder has muscles that cant remain contracted up to longer period )and then voluntary and involuntary it is excreted through urethra .

The process of passing urine is called Micturition .
