Question
The hypothalamusAis a region in the neck involved in hormone production and secretion.Bplays a major role in maintaining an organism’s stable internal body temperature.
Solution
The hypothalamus is a small region located at the base of the brain, near the pituitary gland. It plays a crucial role in many important functions, including:
-
Hormone production: The hypothalamus produces and releases a variety of hormones that can stimulate or inhibit different bodily functions. These hormones can affect growth, metabolism, body temperature, and more.
-
Maintaining body temperature: The hypothalamus helps maintain the body's internal balance, or homeostasis. One of the ways it does this is by regulating body temperature. If the body becomes too hot or too cold, the hypothalamus sends signals to adjust and return to a normal temperature.
So, the correct answer is B. The hypothalamus plays a major role in maintaining an organism’s stable internal body temperature. It is not located in the neck, but in the brain, and it is involved in hormone production and secretion.

As you know, the hypothalamus is thebasal part of diencephalon, forebrain(Figure 22.1) and it regulates a widespectrum of body functions. It containsseveral groups of neurosecretory cellscalled nuclei which produce hormones.These hormones regulate the synthesis and secretion of pituitaryhormones. However, the hormones produced by hypothalamus are oftwo types, the releasing hormones (which stimulate secretion of pituitaryhormones) and the inhibiting hormones (which inhibit secretions ofpituitary hormones). For example a hypothalamic hormone calledGonadotrophin releasing hormone (GnRH) stimulates the pituitarysynthesis and release of gonadotrophins. On the other hand, somatostatinfrom the hypothalamus inhibits the release of growth hormone from thepituitary. These hormones originating in the hypothalamic neurons, passthrough axons and are released from their nerve endings. These hormonesreach the pituitary gland through a portal circulatory system and regulatethe functions of the anterior pituitary. The posterior pituitary is underthe direct neural regulation of the hypothalamus (Figure 22.2)
The hypothalamus(A) synthesizes all of the hormones produced by the pituitarygland.(B) influences the function of only one lobe of the pituitarygland.(C) produces only inhibitory hormones.(D) regulates both reproduction and body temperature.
