• Resting membrane potential maintenance

  58524 Resting membrane potential maintenance Explain how the axonal membrane potential is restored following action potential depolarization. Describe how resting ionic distributions are maintained.

• EPSPs and IPSPs

  Stanfield Forces Determining the Resting Membrane Potential: The membrane potential that is held by the cell during rest is called resting membrane potential.

• Nervous System

  Transport proteins called (10) _____ - _____ _____ counter the leakage of ions across the neuronal membrane and maintain the resting membrane potential.

• Problems with Potassium

  membrane potential more negative (ie decreasing the resting membrane potential).

• Action Potential and Ion Regulation

  Regulation of ions during resting potential, action potential and restoration of membrane potential is discussed.

• Pathophysiology: Hypokalemia

  In the heart, hypokalemia causes hyperpolarization in the myocytes' resting membrane potential.

• Cell Biology

  In a cell with a resting membrane potential what is the distribution of K+, Na+, and Ca2+ ions (more extracellulary or intracellurally). The resting membrane potential arises from an unequal distribution of ions across the cell's membrane.

• Discussion on action potentials

  The movement is controlled by membrane proteins specific to those ions. The whole process can be simplified to four main parts: 1) Resting potential- when the neuron is not stimulated, it is said to be at resting potential.

• Factors Affecting Action Potentials

  These IPSPs hyperpolarize the membrane. That is, they make the resting potential even more negative than it normally is. If we assume a resting potential of about -70 mV, then an IPSPs might make the potential -90mV.
