Which of the following parts of the body/glands maintains the body temperature?

Hypothalamus

The correct answer is Option (4)- Hypothalamus

The part of the body/gland that plays a crucial role in maintaining body temperature is the Hypothalamus.

Explanation:

The hypothalamus is a small region located at the base of the brain, and it acts as a control center for various physiological processes, including the regulation of body temperature. It receives signals from temperature receptors in the skin and internal organs, allowing it to monitor the body's temperature.

When the body temperature deviates from the set point, the hypothalamus initiates responses to bring it back to normal. If the body is too warm, the hypothalamus triggers mechanisms such as sweating and dilation of blood vessels to release excess heat. Conversely, if the body is too cold, the hypothalamus activates responses like shivering and constriction of blood vessels to conserve heat.

While other glands like the thyroid, pituitary, and adrenal glands are involved in various aspects of metabolism, hormone regulation, and stress responses, the primary control of body temperature is orchestrated by the hypothalamus.
