Solved by a verified expert:Describe actions at the neural cell membrane including the resting membrane potential and the action potentialWhat maintains the resting membrane potential, and what forces work against it?What ionic movements occur (in and out of the cell) in the course of the action potential and what changes in membrane charge (potential) occur at depolarization, re-polarization and hyper-polarization?What role does myelin play in the movement of the action potential?When the action potential reaches the end of the axon, which ion comes rushing in to prompt neurotransmitter release into the synaptic cleft?how do astrocytes contribute to the GABA and glutamate neurotransmitter systems
