Question

Name the hormones responsible for:
a. Development of a mustache and beard in male.
b. Controlling the uterus changes in the menstrual cycle.
c. Increasing blood glucose level.
d. Maintaining water and electrolyte balance

Answer 1

The hormone responsible for the development of mustache and beard is a steroid hormone secreted by Leydig cells. Hormones that control uterus changes in the menstrual cycle is a steroid hormone of the ovary. The hormone responsible for increased blood glucose level is a peptide hormone secreted by alpha cells of pancreas. The hormone which maintains water and electrolyte balance is a peptide hormone synthesized in hypothalamus.

Complete answer:
The hormones that are responsible for-
A. Development of mustache and beard in male:
Testosterone is the steroids hormone that is secreted by Leydig cells, which are the endocrine part of the testis. Testosterone is also known as male hormones or masculinizing hormones. It has the following important functions: to cause the proper development of secondary sexual characteristics like beard and mustache, aggressive nature, massive voice, and stronger build of body and shoulders.

B. Controlling the uterus changes in menstrual cycle:
Estrogen are the group of steroid hormones secreted by the graafian follicle. It is also known as a female or feminizing hormone. It has the following functions: to cause the proper development of genitalia such as uterus vagina, to cause the initial preparation of endometrium, to cause the onset of the menstrual cycle.

C. Increasing blood glucose level:
Glucagon are the hormones secreted by the alpha cells of islets of Langerhans. This hormone increases the blood glucose level as it stimulates glycogenolysis and gluconeogenesis.

D. Maintaining water and electrolyte balance:
Antidiuretic hormone (ADH) is a protein hormone produced in the hypothalamus and released by the posterior pituitary. It is also known as Vasopressin. It maintains fluid and electrolyte balance.

Note: Testosterone is the male hormone and it causes the development of male characters (mustache and beard) also it causes the development of male genitalia. Estrogen is the female hormone which controls the uterus changes during menstrual cycle and also develops the female genitalia. Glucagon is called a hyperglycaemic factor as it increases blood sugar (glucose level). ADH maintains normal body fluid (water and electrolyte level).
