Detailed explanation-2: -First, within cells, electrical signals are conveyed along the cell membrane. Second, for communication between cells, the electrical signals generally are converted into chemical signals conveyed by small messenger molecules called neurotransmitters.

Detailed explanation-3: -Neuropeptides are a type of neurotransmitters. Neuropeptides are short-chain amino acids and neurotransmitters are polypeptide molecules. The production of neuropeptides occurs in the cell body of the neuron while the production of neurotransmitters occurs at the axon terminal of presynaptic neurons.

Detailed explanation-4: -Answer and Explanation: The best answer is C. They move in a random manner. Neurotransmitters are chemical messenger substances.
