Question

The body temperature regulatory centre in the brain is:
A. Cerebellum
B. Corpus callosum
C. Hypothalamus
D. Hippocampus

Answer 1

Hint: It also maintains daily physiological cycles, controlling appetite, managing sexual behavior, regulating sexual behavior, regulating emotional responses. This gland is located at the base of the brain, near the pituitary gland.

Complete Answer:
The hypothalamus is a small region of the brain which is located at the base of the brain, near the pituitary gland.
Though it is very small, the hypothalamus plays an important role in many important functions, including:
• Releasing hormones
• Regulating body temperature
• Maintaining daily physiological cycles
• Controlling appetite
• Managing of sexual behavior
• Regulating emotional responses

So, the correct answer is option (C) i.e., Hypothalamus.

Additional information: The hypothalamus has three main regions. Each one contains different nuclei. These are clusters of neurons that perform vital functions, such as releasing hormones.
1. Anterior region: Some of the most important hormones produced in the anterior region include: Corticotropin-releasing hormone (CRH), Thyrotropin-releasing hormone (TRH), Gonadotropin-releasing hormone (GnRH), Oxytocin, Vasopressin, Somatostatin.
The anterior region of the hypothalamus also helps regulate body temperature through sweat. It also maintains circadian rhythms.
2. Middle region: The ventromedial nucleus helps to control the appetite, whereas the arcuate nucleus is involved in releasing growth hormone-releasing hormone (GHRH). GHRH can stimulate the pituitary gland to produce growth hormone.
3. Posterior region: The posterior hypothalamic nucleus helps in regulating the body temperature by causing shivering and blocking sweat production.

Note: The hypothalamus contains neurons that react strongly to steroids and glucocorticoids – (the steroid hormones of the adrenal gland, released in response to ACTH). It also contains specialized glucose-sensitive neurons, which are important for appetite.
