Explain the role of pituitary gland & hypothalamus in biological clock in detail.



I will mark u the brainliest

Answer 1

HI,
pituitary gland and hypothalamus glands are major endocrine glands.

1)HYPOTHALAMUS:
small structure at the base of the brain.
regulates many body functions, including appetite and body temperature. regulates the pituitary gland.

FUNCTIONS OF THE DIFFERENT TYPES OF HORMONES IN HYPOTHALAMUS .
1)hormone: thyrotrophin releasing hormone.
=>main tissue acted on hormone: anterior pituitary.
=>main function of hormone: stimulates release of thyroid stimulating hormone from anterior pituitary.

2) hormone:somatostain
=>main tissue acted on by hormone: anterior pituitary.
=>main function of hormone: inhibitory hormone that prevents release of hormones such as growth hormone from anterior pituitary.

3) hormone:gonadotrophin releasing hormone
=>main tissue acted on by hormone: anterior pituitary.
=>main function of hormone:stimulates release of FSH and LH .

4)hormone: corticotrophin releasing hormone.
=>main tissue acted on by hormone: anterior pituitary.
=>main function of hormone: stimulates ACTH .

5)hormone: GHRH.
=>main tissue acted on by hormone: anterior pituitary .
=>main function of hormone: stimulates release of growth hormone.

PITUITARY GLAND:
a sort of master gland. it is cherry sized endocrine gland.the hormone it secretes affect the growth and secretion of other endocrine gland. the real boss is the HYPOTHALAMUS.
1)hormone: growth hormone
=>main function: brings about general growth ,stimulates other endocrine gland.

2)Hormone: FSH
=>main function: FSH directs estrogen for formation of ovum in uterus of females.while in males directs testosterone to stimulates sperm sacs to produce sperm.

3)Hormone: LH
=>main function: LH causes the egg to burst out and flow into the fallopian tubes.
