Exocytosis. Exocytosis is the reverse of endocytosis. Quatities of material are expelled from the cell without ever passing through the membrane as individual molecules. By using the processes of endocytosis and exocytosis, some specialized types of cells move large amounts of bulk material into and out of themselves.
Nerve cells at rest have an electrical charge across their membranes: the outside of the cell is positively charged and the inside of the cell is negatively charged. Depolarization occurs when the nerve cell reverses these charges; to change them back to an at-rest state, the neuron sends another electrical signal. The entire process occurs when the cell allows specific ions to flow into and out of the cell.
