Gland and its Hormones CSIR NET JRF study material


If you already attened exams like CSIR, ICMR, GATE, DBT NET JRF you will always come across questions about gland system in own body and hormones released by them and there related function here you find list of glands in our body and there function
Gland Hormone Functions
HypothalamusReleasing and inhibiting hormones and factors
Posterior pituitary hormones produced here
Control of another pituitary hormones
Posterior pituitary glandReceives hormones from hypothalamus no hormones synthesised here
stores and secretes the following:
Antidiuretic hormone (ADH) (vasopressin)
Ejection of milk from mammary gland, contraction of uterus during birth
Reduction of urine secretion by kidney
Anterior pituitary glandFollicle stimulating hormone (FSH)
Luteinising hormone (LH)
Thyroid stimulating hormone (TSH)
Adrenocorticotrophic hormone (ACTH or corticotrophin)
Growth hormone (GH)
In male, stimulate spermatogenesis
In female, growth of ovarian follicles
In male testosterone secretion
In female secretion of oestrogen and progesterone, ovulation and maintenance of corpus luteum
Stimulates milk production and secretion
Synthesis and secretion of thyroid hormones growth of thyroid glands.
Synthesis and secretion of adrenal cortex hormones growth of gland
Protein synthesis, growth, especially of bone of limbs
Parathyroid glandParathormoneIncreases blood calcium level
Decreases blood phosphate level
Thyroid glandTriiodothyronine (T3)and thyroxine (T4)
Regulation of basal metabolic rate, growth and development
Decreases blood calcium level
Adrenal cortexGlucocorticoids (cortisol)
Mineralocorticoids (aldosterone)
Protein breakdown, glucose/glycogen synthesis,adaptation to stress, anti-inflammatory/allergy effects
Na+ retention in kidney, Na+ and K+ ratios in extracellular and intracellular fluids, raises blood pressure
Adrenal medullaAdrenaline (epinephrine)
Noradrenaline (norepinephrine)
Increase rate and force of heartbeat, constriction of skin and gut capillaries
Dilation of arterioles of heart and skeletal muscles, raising blood glucose level
General constriction of small arteries, raising of blood pressure
Islets of LangerhansInsulin (beta cells)
Glucagon (alpha cells)
Decreases blood glucose level, increases glucose and amino acid uptake and utilisation by cells
Increases blood glucose level, breakdown of glucogen to glucose in liver
Cholecystokinin (Pancreozymin)
Secretion of gastric juices
Secretion of pancreatic juice
Inhibits gastric secretion
Emptying of gall bladder and release of pancreatic juice in to duodenum
Oestrogens(17 Beta-oestradiol)
Conversion of angiotensinogen into angiotensin
Female secondary sex characteristics, oestrous cycle
Gestation, inhibition of ovulation
Corpus luteumProgesterone and oestrogen
Progesterone ans oestrogen
Growth and development of uterus
Foetal development
PlacentaChorionic gonadotrophin
Human placental lactogen
Maintenance of corpus luteum
Stimulates mammary growth
TestisTestosteroneMale secondary sexual characteristics
