Solution

The correct option is C TRH
The hypothalamus is the basal part of the diencephalon, forebrain.
When a young child's body temperature drops, the hypothalamus produces TRH( thyrotropin-releasing hormone)hormone.
Thyroid-releasing hormone (TRH) from the hypothalamus stimulates TSH(Thyroid stimulating hormone) from the pituitary, which stimulates thyroid hormone release from the thyroid gland.
Thyroid hormone causes an increase in BMR(Basal metabolic cate) and increases in BMR results in an increase in body temperature to normal.
Hence When a young child's body temperature drops, the hypothalamus produces TRH( thyrotropin-releasing hormone)hormone.
So, the correct answer is 'TRH'.

Q. .......... is a hormone produced by hypothalamus, which is responsible for the release of gonadotropins.

Q. Testosterone is a steroid hormone produced by all vertebrate animals and, in humans and other mammals, it is secreted in large amounts by the testes of males and to a much lesser extent, the ovaries of females. In adult males, testosterone plays a key role in the development of reproductive organs and it promotes the secondary sexual characteristics of body and facial hair, increased muscle and bone mass, and a deep voice. Testosterone, like all hormones, works via long distance signaling and is regulated by other hormones as illustrated below:

Figure 1:

Testosterone regulation by cooperation between the hypothalamus, pituitary, and testicular endocrine glands. The major regulatory hormones involved are luteinizing hormone (LH), follicle-stimulating hormone (FSH) and gonadotropin-releasing hormone (GnRH).

When testosterone levels are low, gonadotropin-releasing hormone (GnRH) is released by the hypothalamus, which in turn stimulates the pituitary gland to release FSH and LH. FSH and LH then stimulate the testis to produce testosterone.
How is homeostasis achieved when testosterone levels begin to rise?
