factors responsible for a negative resting membrane potential include: check all that apply:   a. Na K pump  b. different carrier proteins  c. uneven distribution of ions  d. difference in permeability of ions  e. high potassium concentration in ECF

Consider the brain and spinal neurons. If you bathed a resting neuron with an excess of potassium ions (for example, more than 40 times higher than normal), what would be the effect on resting membrane potential?

The negatively charged intracellular environment and resulting resting membranepotential of neurons and muscle cells fundamentally develops because of:A. the presence of a high extracellular potassium concentration.B. the presence of negatively charged intracellular proteins.C. the high electron concentration found in the extracellular fluidsD. the presence of voltage-gated-sodium channells

Our patient cannot remove potassium from their extracellular fluid. This is known as hyperkalemia. Describehow the two things above, the resting membrane potential and the action potential, would be different in someone with hyperkalemia.

Explain why alterations in potassium concentrations have more powerful effects on membrane resting potentials than alterations in sodium ions

Answer to question 6 please

Describe two things that contribute to the resting membrane potential

I need help please

If the resistance of the neuronal membrane goes from 250 Mᘯ to 500 Mᘯ, which of the following is most likely to occur?   Current will doble   Current will quadruple   Current will decrease by half   Current will increase by 1/4th

4) A neuron with ionic gradients described in the table below receives a synaptic input that opens channels that conduct Na. If the resting membrane potential is –60 mV and the change in conductance is 20 nS, what is the magnitude of the Na current (INa)? Concentration (mM) Ion Extracellular Intracellular Na+ 150 8 K+ 3.5 150
