Endocrinology Flashcards
what is the anterior portion of the pituitary called
adenohypophysis
where does the adenohypophysis arise from
rathke’s pouch
what is the connection between the adenohypophysis to the hypothalamus
hypophysial portal system
location of pituitary gland
sella turcica
what hormones are from the adenohypophysis
- GH aka somatotropin
- TSH aka thyrotrophic SH
- prolactin aka luteotrophic
- FSH
- LH
- ACTH
- MSH
what is the posterior portion
neurohypophysis
neurohypophysis arises from
neural ectoderm
what is the connection between the neurohypophysis to the hypothalamus
infundibulum
hormones of neurohypophysis
- vasopressin (ADH)
- oxytocin
- ADH
what does ADH do
controls water balance (retention/excretion)
deficiency in ADH is due to
diabetes insipidus
what does oxytocin do
milk let down; contracts uterus; stimulated by suckling
what are the perifpheral orangs
pancreas, parathyroid, adrenal cortex, adrenal medulla
function of pancreas
regulates blood sugar
what hormones are from pancreas
insulin from beta cells
glucagon from alpha cells
where do pancreas hormones go
insulin: many
glucagon: liver
function of parathyroid, vitamin d, thyroid
regulate blood calcium within bone
parathyroid hormones
parathormone
thyroid hormones
calcitonin, T3, T4
where is calcitonin secreted from
parafollicular cells
where is T3, T4 secreted from
follicular cells
what is the effect of parathormone
increase blood ca2+ and decrease phosphorus
what is the effect of calcitonin
decrease blood ca2+ and increase phosphorus
what is the effect of T3 and T4
upregulate metabolism
