Question

Explanation:

When a person is physically dependent on opioids, the body's noradrenergic system undergoes adaptations. Opioid use suppresses the locus - coeruleus, a major source of noradrenaline in the brain. This leads to a decreased amount of noradrenaline. To compensate for the reduced noradrenaline activity, the number of noradrenaline receptors is increased.

Answer:

A. A DECREASED amount of noradrenaline is present.
C. An INCREASED number of noradrenaline receptors are present.
