The resting membrane potential is a negative value because of:

Explain the forces that produce the resting membrane potential?

Dr. Brainy creates a nerve cell that is only permeable to Caesium ions (Cs+1) at rest. She measures that the concentration of Caesium is 400mM outside the cell and only 50 mM inside the cell. She calculates the Equilibrium potential for Cs+1 (Ecs) to be +35 mV. If the cell is only permeable to Cs, the resting membrane potential will be: +58 mV 0 mV +35 mV -58 mV

Explain why reticular fibers are also termed as argyrophilic fibers and lattice fibers

The change of membrane potential from -70mV to -90 mV is hyperpolarization. T/F

13) Draw a graph representing the changes in membrane potential across the axonal membrane before, during, and after an action potential. On your graph, use a highlighter to clearly indicate for which portions of your graph the letter corresponding to each cellular event listed below belongs. List of cellular events: A) All K* channels open B) All Na* channels close C) The Na*/K* ATPase cotransporter transports Na* and K* across the membrane. D) All Na* channels open E) The threshold value of membrane potential is attained. F) All K* channels close G) Some Na* channels open Your graph:

List the Forces influencing sodium and potassium ions at the resting membrane potential?

A True OUTSIDE CELL This cell is at rest. False INSIDE CELL C D T E

Is the resting membrane potential the bases of conduction in nerves and muscle fibers and the presecutors of contraction in muscles?

What is the resting membrane potential? What three factors create the resting membrane potential?
