Define and describe membrane potential and give its value in neurons. Give the relative concentrations for sodium and potassium ions inside and outside of a neuron at rest. Describe any movements of sodium and potassium ions that occur while a neuron is at rest. Which ion has the greatest permeability? Why? Is there any movement of ions across the plasma membrane? If so, which ion is moving in which direction and how?

Step 1
It is determined by the concentration gradient of ions across the membrane and the membrane's permeability to each type of ion. ** Show more…

Starting with a neuron at resting membrane potential, explain the movement of sodium ions during an action potential in terms of the 5 principles in the "Flow Down Gradients" core concept. Be sure to address each principle with respect to sodium ions throughout the action potential.

The transport of ions across cell membranes is a key part of the processes of generation and conduction of action potentials in neurons. a) Why do ions require an integral membrane protein in order to pass across neuronal cell membranes? Briefly discuss the specific ion channels and transporters that are involved in the generation and conduction of a neuronal action potential, and indicate whether the protein is involved in facilitated diffusion or active transport of ions. How does myelination of the axon of a neuron affect the transport of ions across the membrane and the conduction of an action potential?
