I don't think there is a very large effect unless your plasma sodium concentration is seriously out of whack. Changes in plasma calcium or potassium concentrations can affect action potentials a lot more than changes in sodium. I guess theoretically increased sodium intake will tend to depolarize everything.
What else can I help you with?
What is a reflax action?
A reflex action is an "automatic" and sometimes involuntary action caused by the presence of a stimulus.The action requires no conscious thought and will happen naturally.An example is someone waving ther hand very close to your face, you will naturally blink.This is a reflex action.
What happen to the speed of moving object when it is pushed in the direction of motion?
When a moving object is pushed in the direction of its motion the speed of the object increases
What is needed to make any action happen?
In science a force is needed....in everyday life a force and usually a motive
A higher concentration of molecules causes a faster chemical reaction This is known as?
This is known as chemical equilibrium. All of the chemicals will want to become stable and this can only happen with equilibrium.
What is evidence how is direct evidence different from inderict evidence?
Direct evidence are visible noticable changes. Indirect evidence is when you might not see the action happen but you do notice the results
What would happen to the equilibrium potential of Na if you change the concentration of K inside the cell?
The equilibrium potential of sodium (Na) is primarily determined by the concentration of Na ions inside and outside the cell, as described by the Nernst equation. Changing the concentration of potassium (K) inside the cell does not directly affect the equilibrium potential of Na. However, alterations in K concentration can influence the overall membrane potential and the activity of sodium channels, which may indirectly affect the dynamics of Na influx during action potentials. Thus, while the Na equilibrium potential remains unchanged, the cell's excitability and response to stimuli could be affected.
When does potential energy increase?
Potential energy increases when an object's position or configuration changes such that it is able to do work due to its stored energy. This can happen when an object is lifted higher against gravity, compressed, stretched, or charged with electrical or magnetic potential.
What happen to barrier potential when temperature increases?
barrier potential P0=(kT/q)*ln(Na*Nd/Ni^2) when T ↑, P0↑.
Is an action potential is a phenomenon that either happens completely or doesn't happen at all?
Yes, an action potential is an all-or-nothing event in which a neuron either fires a full strength signal or does not fire at all. This is due to the threshold that needs to be reached in order for the action potential to occur.
What happen to the potential energy if its height increases?
If the height of an object increases, its potential energy also increases. This is because potential energy is directly proportional to the height of the object above a reference point, such as the ground. As the object is raised to a higher position, it gains more potential energy due to the increased distance it can potentially fall from.
What will happen to the potential and kinetic energy as the ball falls?
As the ball falls, its potential energy will decrease while its kinetic energy will increase. This is because potential energy is converted to kinetic energy as the ball falls due to the force of gravity acting on it.
What would most likely happen to the action potential, if a neuron lost its myelin sheath?
The actional potential would not reach the axon terminals.
What would happen to the resting membrane potential of a neuron if sodium were allowed to travel freely down its concentration gradient?
The cell will depolarise
According to the all or none principle what would happen if a cell were depolarized twice the normal amount needed to produce an action potential?
If a cell were depolarized twice the normal amount needed to produce an action potential, it would still only produce a single action potential. The all-or-none principle states that once the threshold for an action potential is reached, the neuron will fire with a fixed amplitude and duration regardless of the strength of the stimulus.
What would happen if the re-uptake of a stimulatory neurotransmitter was blocked?
The action of the excitatory neurotransmitter will increase, since its concentration in the synapse will rise.
What happen during the rising phase of an action potential?
During the rising phase of an action potential, voltage-gated sodium channels open in response to a depolarizing stimulus. This allows sodium ions to rush into the cell, causing a rapid depolarization of the cell membrane. This results in the cell reaching its threshold and firing an action potential.
In a cell that contains saltwater and pure water surrounds the cell what is most likely to happen?
The cell is in a hypotonic solution, which mean there is more concentration of salt inside than out. Then osmosis works to equalize the concentrations in both the cell and outside solution. In this case, the pure water would rush into the cell to dilute the salt concentration to match the outside concentration. But if too much water enters the cell, the pressure increases and the cell membrane has the potential to burst.
