Termini in questo insieme (31)
what hormones are produced by the posterior pituitary (neurohyphosis)
oxytocin and ADH
stimulates contractions and milk ejection
oxytocin
increases water reabsorption in kidneys
reduce urine output
ADH
what hormones are produced by the anterior pituitary (adrenohyphosis)
GH, TSH, ACTH, FSH, LH, prolactin
what are tropic hormones
hormones that stimulate the release of another hormone
stimulates growth, protein synthesis, and cell replication
growth hormone
stimulates thyroid hormone release
thyroid stimulating hormone - TSH
stimulates adrenal cortex to release corticosteroids
adrenocortitropic hormone
stimulates gamete (sex cell) production
follicle stimulating hormone (FSH)
ovulation and hormone production
leuitinzing hormone - LH
stimulates lactation
prolactin
regulates metabolism, growth, and development
thyroid gland
increases metabolic rate
thyroid hormone
decreases blood calcium levels, inhibits osteoclasts, increases calcium excretion
calcitonin
regulates blood calcium levels
parathyroid gland
increases blood calcium levels, stimulates osteoclasts
parathyroid hormone
what does increases osteoclast activity (increased PTH) lead to
bone resorption (breaking down bone tissue)
where are the adrenal glands loated
on top of kidneys
what does ACTH stimulate
the adrenal cortex
what is produced in the adrenal glomerulosa
aldosterone (mineralcoriticoids)
what is produced in the adrenal fasciculata
coritsol
what is produced in the adrenal reticularis
sex hormones
what is produced in the adrenal medulla
epinephrine and norepinephrine
increases blood sodium levels
aldosterone
regulates stress and metabolist
cortisol
what increases blood glucose levels
glucagon (alpha cells)
glycogenolysis
break down of stored glycogen into glucose to raise glucose levels
gluconeogenesis
production of glucose from non carbohydrates (amino acids) to raise glucose levels
glycogenesis
production of glycogen from glucose
glycolysis
splitting glucose directly into ATP for energy
what causes goiter
low iodine levels reduce T3 and T4 hormones , increases TSH , thyroglobulin accumulation causes goiter
