This is the Biology Gk study material section on “Summary of Endocrine gland, their Hormones and Effects” with explanation for various interview, competitive examination and entrance test. Solved examples with detailed answer description, explanation are given and it would be easy to understand.
|SUMMARY OF DIFFERENT ENDOCRINE GLAND, THEIR HORMONES AND EFFECTS|
Controls growth and metabolism of protein. Deficiency causes dwarfism, excess causes gigantism and acromegaly
Stimulates adrenal cortex
Suppresses secretion of insulin
Affects growth of Graafian follicles in ovary and seminiferous tubules In testis
Affects production and release of gonadal hormones
Affects mammary glands and milk production
Affects pigments in skin chromatophores
Stimulates contraction of uterine muscles and secretion of milk
Regulates blood pressure and water loss by kidneys.
|Thyroid||Thyroxine||Increases O2 consunption or basal metabolic rate. Deficiency leads to cretinism in children and myxedema in adults. Hyperthyroidism causes goiter formation and exopthalmia|
|Parathyroids||Parathormone||Regulates calcium and phosphorous metabolism|
|Thymus||Regulates growth. Sexual maturity and immunity|
|Islets of Langerhans
(a) Beta cells
(b) Alfa cells
Oxidation of glucoseand its conversion into
Glycogen. Deficiency causes diabetes mellitus
Conversion of liver glycogen into blood.
Conversion of proteion to carbohydrates.
Metabolism of sodium and potassium
Stimulates male characteristics.
Supplement action of sympathetic nervous system during emergencies
Norepinephrine Regulates normal blood pressure.
Development and maintenance of male sex characters.
Development and maintenance of femal sex characteristics.
Changes associated with pregnancy
Acts with other hormones to maintain pregnancy
Relaxes pelvic ligaments at child birth
Induces gastric secretion.
Slows down gastric secretion
Stimulates pancreatic secretion
Stimulates bile secretion
