Answer 1

Serotonin is not exclusively found in the brain and has various physiological roles in the body.

Step-by-step explanation:

The false statement is D) Serotonin is exclusively found in the brain and has no impact on other physiological processes in the body. Serotonin is actually found in various parts of the body, including the cardiovascular tissue, endothelial cells, blood cells, and the central nervous system. It plays a role in mood regulation, sleep, appetite, and has been associated with conditions like depression and anxiety. Selective serotonin reuptake inhibitors (SSRIs) are a class of antidepressant medications that increase serotonin levels in the brain.
