Solution

The correct option is C Non-nutrient chemicals produced by the body in trace amount that act as intercellular messenger are known as hormones
Hormones are non-nutrient chemicals which act as intercellular messengers and are produced in trace amounts.
In addition to the endocrine glands, organs in the body like gastrointestinal tract, heart, kidney, and liver also produce hormones.
The releasing and inhibitory hormones are produced by the hypothalamus.
Adenohypophysis is not under direct neural regulation, it is under the control of the hypothalamic hormones brought by the portal system.

Q. Hormones are non-nutrients chemicals which act as .............. messengers and are produced in ........... amount.

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?

Which of these is true for hypothalamus?

(A) Controls the pituitary gland.

(B) Mainly responsible for calcium regulation.

(D) Controls the entire endocrine system.
