For a nerve impulse to move from one neuron to the next.,it must pass though the __ gap cerebrospinal fluid neurotransmitter synapse

## Step 1<br />The problem is asking us to identify the correct term that describes the gap through which a nerve impulse must pass from one neuron to the next. The options provided are "gap", "cerebrospinal fluid", "neurotransmitter", and "synapse".<br /><br />## Step 2<br />The term "gap" is too vague and does not specifically refer to the space between neurons.<br /><br />## Step 3<br />"Cerebrospinal fluid" is a clear, colorless body fluid found in the brain and spinal cord. It does not directly facilitate the transmission of nerve impulses between neurons.<br /><br />## Step 4<br />"Neurotransmitter" is a chemical substance that is released at the end of a nerve fiber by the arrival of a nerve impulse and, by diffusing across the synapse or junction, causes the transfer of the impulse to another nerve fiber, a muscle fiber, or some other structure.<br /><br />## Step 5<br />"Synapse" is the correct term. It refers to the structure that permits a neuron to pass an electrical or chemical signal to another neuron. The synapse is the gap between neurons where neurotransmitters are released to carry the nerve impulse from one neuron to the next.
