No, the correct answer is C. chemicals. When a nerve impulse reaches a synapse, which is the tiny gap between two nerve cells, the nerve cell that generated the impulse releases chemical substances known as neurotransmitters. These neurotransmitters diffuse across the synapse and bind to receptor proteins on the membrane of the next nerve cell, thereby transmitting the impulse from one cell to another. This process of transferring the nerve impulse through the release and binding of neurotransmitters is called synaptic transmission.
