Cocaine acts in the nervous system by blocking
a. the dopamine transporter.
b. the serotonin transporter.
c. the norepinephrine transporter.
d. voltage-gated sodium channels in axons.
e. all of the above

The correct option is: e. All of the above

Explanation:

Cocaine is a habit-forming illegal recreational drug and a very strong nervous system stimulant. The effects of this drug include euphoria, hallucinations, paranoid delusions, increased heart rate, large pupils,  perspiration, itching and high body temperature.

Cocaine acts on the nervous systems of the human beings by blocking the reuptake of dopamine, serotonin, and norepinephrine neurotransmitters in the brain.

It also interferes with the action potential propagation by blocking the voltage-gated sodium channels.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
