Q.Which part of the human brain is concerned with the regulation of body temperature ?

The hypothalamus, a small region at the base of the forebrain, houses the thermoregulatory centre that controls and maintains normal body temperature.

The hypothalamus is a vital coordinating centre of the brain that links the nervous system to the endocrine system (via the pituitary gland) and regulates many homeostatic activities. Among its functions, it contains a specific thermoregulatory centre that continuously monitors blood temperature and, together with peripheral thermoreceptors in the skin, triggers responses to keep body temperature constant — such as inducing sweating and vasodilation when the body is too warm, or shivering (increased muscular activity) and vasoconstriction when the body is too cold. The hypothalamus similarly regulates hunger, thirst, sleep-wake cycles, and emotional responses. In contrast, the medulla oblongata controls involuntary vital functions like heart rate, breathing rate, and reflexes such as coughing and sneezing; the cerebellum coordinates voluntar …
