Who does not move across axons. a. electrons and irons b. neither electrons nor axons c. electrons d. ions

An axon is also called as nerve fiber which is a long slender projection like part of a nerve cell (neuron).

The function of axon is to conducts electrical impulses away from the neuron's cell body.

It does not allows electrons or other axons to move across the axons. Instead it only allows the ions to get transferred.

Ions move across axons because the ions flow beyond the layer inside the cell or outside the cell. However, the action potential movement is from the soma which is the cell body to the bouton which is the end of the axon. The neuron keeps a resting membrane potential because inside example the neuron of potassium (K+), the potassium has great consistency.

There is a concentration gradient endeavoring to push potassium outside the cell. Alike powers will try to move sodium ions inside the neuron.
