What is the function of the hypothalamus?
A
the master gland
B
controls all other endocrine glands
C
senses the hormone levels in the blood
D
helps you go to sleep
Explanation: 

Detailed explanation-1: -The hypothalamus plays a critical role in regulating blood glucose levels due to its ability to sense, integrate and respond to changes in circulating signals.

Detailed explanation-2: -The hypothalamus is the link between the endocrine and nervous systems. The hypothalamus produces releasing and inhibiting hormones, which stop and start the production of other hormones throughout the body.

Detailed explanation-3: -The posterior region is also called the mammillary region. The posterior hypothalamic nucleus and mammillary nucleus are its main nuclei. The posterior hypothalamic nucleus helps regulate body temperature by causing shivering and blocking sweat production. The mammillary nucleus is involved in memory function.

Detailed explanation-4: -For each system, the hypothalamus secretes releasing hormones (i.e., CRH, GnRH, and TRH) that act on the pituitary gland. In response to those stimuli, the pituitary gland releases ACTH, gonadotropins (i.e., LH and FSH), or TSH. ACTH activates the adrenal glands to release cortisol, which induces metabolic effects.

Detailed explanation-5: -The thyrotropin-releasing hormone (TRH), gonadotropin-releasing hormone (GnRH), growth hormone-releasing hormone (GHRH), corticotropin-releasing hormone (CRH), somatostatin, and dopamine are released from the hypothalamus into the blood and travel to the anterior pituitary.
