Final answer:
The hypothalamus is involved in multiple regulatory processes in the body, not just body weight regulation.
Step-by-step explanation:
The statement that the hypothalamus is only involved in the regulation of body weight is false.
The hypothalamus, located below the thalamus in the brain, plays a crucial role in regulating various bodily functions, including body weight. However, it is not limited to just this function. The hypothalamus also controls important behaviors such as food and water intake, energy expenditure, body temperature, and circadian rhythms.
Therefore, the hypothalamus is involved in multiple regulatory processes in the body, not just body weight regulation.
