    [5] Sodium Ions




    The electrical and chemical process of transferring nerve impulses between neurons and among neurons and other neuron networks is called a "synapse." Thus your synapses are "biological switches" that transmit "electro-chemical messages" to and from your brain and nervous system.

    Each synapse is made up of two parts. One is a knoblike "synaptic bulb" at the end of the transmitting neuron. The other part is the "receptor region" on the membrane of the target cell. This diagram shows a synaptic bulb in action at the end of an "axon terminal fiber" releasing its sodium ions.
