Question

Which part of brain is supposed to be damaged if in an accident, a person lose control of water balance, hunger and body temperature?

• A. Cerebellum
• B. Hypothalamus
• C. Medula oblongata
• D. Corpora quadrigemina

Answer 1

Answer: (B)

Hypothalamus

The hypothalamus is the control centre for many autonomic functions of the peripheral nervous system. Connections with structures of the endocrine and nervous systems enable the hypothalamus to play a vital role in maintaining homeostasis. The hormones produced by this area of the brain govern body temperature, thirst, hunger, sleep, circadian rhythm, moods, sex drive, and the release of other hormones in the body. Hence, if hypothalamus is damaged in an accident, control of water balance, hunger and body temperature will be lost.
