I am aware about some basics of Saltatory conduction of nerve impulses. I know that the nerve impulses(ionic flow and the depolarization) are transferred from the node to the node in myelinated nerve fibers instead in the non-myelinated fibers the ionic flow and the depolarization are repeated along the entire length. Thus the saltatory conduction is faster.
Also why is it so that the myelinated nerve fibers require less energy of activation then the non-myelinated ones?
My book says that due to rise in the temperature the conduction of nerve impulses accelerates . I would also like to know the reason for the same.
