Question
Answer
Posterior pituitary gland   2 hormones released (Antidiuretic hormone ADH & Oxytocin)  
🗑
ADH(antidiuretic hormone)   Increase h2o absorption from kidney raise B/P.  
🗑
Oxytocin   Stimulates contraction of pregnant uterus &release of breast milk after childbirth.  
🗑
Anterior Pituitary   6 hormones released, (GH), Prolactin, (TSH), (ACTH), (LH), & (FSH).  
🗑
(AP)-Somatotropin(GH)   stimulates bone & muscle growth, promotes protein synthesis & fat mobilization.  
🗑
(AP)-Prolactin   Promotes production & secretion of milk after childbirth.  
🗑
(AP)-Thyroid-stimulating hormone(TSH)   Stimulates production & secretion off thyroid hormones.  
🗑
(AP)-Adrenocorticotropic hormone(ACTH)   stimulates adrenal cortex to secrete cortisol & other steroids.  
🗑
(AP)-Luteinizing hormone(LH-females) & Interstitial cell-stimulating hormone (ICSH-males)   Initiates ovulation & secretion off sex hormones in both genders.  
🗑
(AP)-Follicle-stimulation hormone(FSH)   Stimulates development of ovum in ovaries & sperm in testes.  
🗑
Thyroid   2 hormones released (thyroxine or T4 & triodothyronine or T3)& Calcitonin.  
🗑
(T)Thyroxine(t4)& triodothyronine(t3)   Increase o2 consumption & heat production, stimulates, increases, & maintains metabolic processes.  
🗑
(T)Calcitonin   Inhibits calcium release from bone, thus lowering blood calcium levels.  
🗑
Parathyroids   Parathyroid hormone(PTH  
🗑
Parathyroid hormone(PTH)   Increase blood calcium by stimulating calcium release from bone, decreases blood phosphate level.  
🗑
Thymus   Stimulates T-cell development in thymus & maintenance in other lymph tissue, involved in some B cells developing into antibody producing plasma cells.  
🗑
Pineal gland   Melatonin  
🗑
Melatonin   involved in circadian rhythms, antigonadotropic effect, exposure to light decreases release.  
🗑
Adrenal Medulla   2 hormones Epinephrine(adrenaline) & Norepinephrine.  
🗑
(AM)Epinephrine(adrenaline)   constricts bld vessels in skin, kidneys, & gut, increases bld supply to heart, brain & skeletal muscles leads to increased HR & B/P, stimulates smooth muscle contraction raises bld glucose levels.  
🗑
(AM)Norepinephrine   constricts bld vessels, increases HR & contraction of cardiac muscles, increases metabolic rate.  
🗑
Adrenal cortex   3 S hormones-corticosteroids(glucocorticoids-sugar), Mineralcorticoids(aldosterone-salt), Gonadocorticoids(androgens male sex hormones).  
🗑
(AC) corticosteroids(glucocorticoids-sugar)   Regulates bld glucose by affecting carb metabolism, affects growth, decreases effects of stress & anti-inflammatory agents.  
🗑
(AC) Mineralcorticoids(aldosterone-salt)   Regulates sodium, h2o & potassium excretion by the kidney.  
🗑
(AC) Gonadocorticoids(androgens male sex hormones)   Contribute to secondary sex characteristics particularly after menopause.  
🗑
Pancreas   2 hormones, Insulin & glucagon.  
🗑
(P)Insulin   Lowers bld sugar, increases glycogen storage in liver, stimulates protein synthesis.  
🗑
(P)Glucagon   Stimulates glycogen breakdown in liver, increases bs(glucose) concentration.  
🗑
Ovary follicle-estrogens   Develop & maintain female sex organs & characteristics, initiates building of uterine lining.  
🗑
Ovary(corpus luteum)   Progesterone & estrogens.  
🗑
Progesterone& estrogens   Influences breast development & menstrual cycles, promotes growth & differentiation of uterine lining, maintains pregnancy.  
🗑
Testes(androgens-testosterone)   Develop & maintain males sex organs & characteristics aid sperm production.  
🗑
