Document Summary

4. 1 resting membrane potential (cid:120) membrane potential is the difference in electrical charge between the inside and the outside of a cell. It"s, however, different for k ions, 90mv of electrostatic pressure would be required to keep intracellular kions from moving down their concentration gradient and leaving the neuron some. 20 mv more than the actual resting potential.

Intermediate levels of stimulation produce intermediate rates of neural firing. Axonal conduction of action potential (cid:120) the conduction of action potentials along an axon differs from the conduction of epsps and ipsps in two important ways. In myelinated axons, ions can pass through the axonal membrane only at the nodes of ranvier the gaps etween adjacent melin segments.
