Anterior Pituitary Gland
A major organ of the endocrine system, the anterior pituitary, is the glandular, anterior lobe that together with the posterior lobe, the (posterior pituitary, also known as the neurohypophysis) makes up the pituitary gland (hypophysis). hypothalamus controls release of hormones from Anterior pituitary by secreting releasing or inhibiting hormones of it's own which travel to capillary bed of Anterior pituitary by small blood vessels. TERM 2
Anterior Pituitary Gland Hormones
DEFINITION 2 hGH - Human Growth HormoneACTH - Adrenocorticotropic HormoneFSH - Follicle Stimulating HormoneLH - Leutinizing HormoneProlactinAll peptide hormones TERM 3
Posterior Pituitary Gland
DEFINITION 3 The posterior pituitary comprises the posterior lobe of the pituitary gland which is part of the endocrine system. Hormones released here produced in hypothalamus TERM 4
Posterior Pituitary Gland Hormones
DEFINITION 4 OxytocinADHPeptide Hormones TERM 5
Adrenal Cortex/Medulla
DEFINITION 5 Adrenal Cortex: Glucocorticoids (cortisol) and mineral corticoids (aldosterone)SteroidsAdrenal Medulla: Catecholamines-Epinephrine and NorepinephrineTyrosine Derivatives
Parathyroid Gland
Four glands found on the back of the thyroid gland TERM 7
Parathyroid Gland Hormones
DEFINITION 7 Parathyroid Hormone: Raises blood calciumPeptide TERM 8
Thyroid Hormones
DEFINITION 8 T3 and T4: Increases basal metabolic rateCalcitonin: lowers blood calciumtyrosine derivatives TERM 9
Pancreatic Hormones
DEFINITION 9 Insulin: promotes entry of glucose into cells, decreasing glucose blood levelGlucagon: Increases glycogenesis and gluconeogenesis, increases glucose blood levelpeptide hormones TERM 10
Ovaries
DEFINITION 10 Estrogens: growth of mother sex organs; causes LH surgeProgesterone: prepares and maintains uterus for pregnancySteroid hormones
LH
Released by Anterior PituitaryPeptide HormoneCauses ovulationstimulates estrogen secretion: LH stimulates theca cells which secrete androgens which become estradiol in presence of FSHstimulates testosterone secretion: Leydig cells secrete testosterone when stimulated by LH TERM 17
TSH
DEFINITION 17 Released by Anterior PituitaryPeptide HormoneStimulates release of T3 and T4 from thyroid gland TERM 18
Prolactin
DEFINITION 18 Released by Anterior PituitaryPeptide HormonePromoties milk production TERM 19
Oxytocin
DEFINITION 19 Released from Posterior Pituitary GlandPeptide HormoneMilk ejection and uterine contraction TERM 20
ADH
DEFINITION 20 Released from Posterior Pituitary GlandPeptide HormoneWater reabsorption in collecting ducts of kidneyconcentrated urine; little outputincrease in BP
Cortisol
Released by Adrenal Cortex in response to stressSteroid Hormone (glucocorticoid)Increased blood levels of carbs, proteins and fatts TERM 22
Aldosterone
DEFINITION 22 Released by Adrenal CortexSteroid (mineral corticoid)Reduces Na+ excretion, increases K+ secretion, raises BP TERM 23
Epinephrine
DEFINITION 23 Released by Adrenal MedullaCatecholaminesstimulates sympathetic action TERM 24
Norepinephrine
DEFINITION 24 Released by Adrenal MedullaCatecholaminesStimulates sympathetic action
