When cocaine is used as a stimulant, it interferes with the CNS at the reuptake of which hormone?
Correct answer: B. Dopamine
- A. Testosterone
- B. Dopamine
- C. Serotonin
- D. Adrenaline
Explanation
Cocaine is a natural stimulant. Stimulants are drugs that stimulate the nervous system and increase alertness and excitement. Excessive dosage of cocaine can cause hallucinations. It interferes with the transportation of dopamine, a neurotransmitter. Dopamine is a chemical messenger and carries signals or nerve impulses from one brain cell to another. From one neuron to another, dopamine is passed through transporter proteins. Cocaine blocks these proteins, which results in high dopamine levels in the synaptic gap, and this can cause damage to brain cells.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
