Which sentence most closely describes neural transmission?
(A) An electric charge is created in the neuron, the charge travels down the cell, and chemicals are released that cross the synapse to the next cell.
(B) A chemical change occurs within the cell, the change causes an electric charge to be produced, and the charge jumps the gap between the nerve cells.
(C) The electric charge produced chemically inside a group of neurons causes chemical changes in surrounding cells.
(D) Neurotransmitters produced in the hindbrain are transmitted to the forebrain, causing electric changes in the cerebral cortex.
(E) Neural transmission is an electrochemical process both inside and outside the cell.

(A) An electric charge is created in the neuron, the charge travels down the cell, and chemicals are released that cross the synapse to the next cell.

Explanation
Neural firing involves an electric charge within the cell and chemical transmission between cells (across the synapse). It is electric within the cell and chemical between the cells. The electric charge does not jump the gap between neurons. The question refers to an individual neuron firing, not a group of neurons. Neurotransmitters are not confined to the hindbrain or the forebrain.
