Norepinephrine, serotonin, and dopamine are all examples of . bodily humors. b. synaptic clefts.

The question is incomplete as it does not have the options which are:

A.bodily humors. B.synaptic clefts. C.neurotransmitters. D.growth hormones.

The correct answer will be option- C

Explanation:

Neurotransmitters are the chemicals released from the neurons at the synaptic junctions which helps in the transmission of the electrical impulse from one neuron to another.

The dopamine, serotonin and nor-epinephrine are the biogenic forms of neurotransmitters which are synthesized from the precursors of the amino acids. These neurotransmitters are produced in producing different functions in the body.

Thus, option- C is the correct answer.
