endocrine glands part 1 Flashcards
source of calcitonin
thyroid parafollicular cells
type of calcitonin
protein
calcitonin is stimulated by
high blood Ca
calcitonin is inhibted by
low blood Ca
Effects of calcitonin
low blood Ca
decreased bone resporton
high calciuria
high phosphatouria
excess of calcitonin
no known effects
deficiency of calcitonin
no known effects
source of PTH
parathyroid chief cells
PTH is stimulated by
low blood Ca
PTH is inihibted by
high blood Ca
Effects of PTH
bone resorption
renal reabsorption
decreased phosphate reabsorption
increased vitamin D
Excess of PTH
Hypercalcemia
hypercalciuria
decreased phosphate
bone resoprtion
Deficiency of PTH
Abnormal conduction
hypocalcemia
tetany
CNS calcification
source of Vitamin D
skin liver kidney diet
Type of Vitamin D
steroud
Vit D stimulated by
low Vit D
low Phosphate
PTH
Vit D inihibited by
low PTH
high phosphate
high Vit D
Effects of Vit D
increased gut Ca and phosphate absorption
Excess of VIT D
hypercalcemia
deficiency of vit D
rickets children
osteomalacia adults
source of insulin
pancreas beta cells
type of insulin
protein
insulin is stimulated by
high blood glucose levels
amino acids
intestinal hormones
insulin is inhibited by
sympathetic tone
catecholamine
somatostatin
effects of insulin
glycogen synthesis
decreased gluconeogenesis
amino acid uptake
lipogenesis
glucose and triglyceride uptake
excess of insulin
hypoglycemia
deficiency of insulin
diabetes mellitus
source of glucagon
pancreas alpha cells
type of glucagon
protein
glucagon stimulated by
exercise
low blood glucose
cortisol
B-adrenergic tone
glucagon is inhibited by
high blood glucose
somatostatin
effects of glucagon
gluconeogenesis proteolysis lipolysis glycogenolysis ketogenesis
excess of glucagon
hyperglycemia
deficiency of glucagon
hypoglycemia
source of ADH
posterior pituitary
type of ADH
protein
ADH stimulated by
osmolality > 280 low ECF volume angiotensin II NICOTINE nausea pain
ADH inhibted by
low osmolality
high ECF volume
ETHANOL
Effects of ADH
increased permeability of collecting tubules
reabsorption of water
vasoconstriction
ACTH release
EXCESS Of ADH
SIADH
hyponatremia
hypertension
DEFICIENCY OF ADH
diabetes insipidus
source of oxytocin
posterior pituitary
type of oxytocin
protein
oxytocin is stimulated by
sucking
crying baby
dilation of uterus
effects of oxytocin
milk letdown
dysmenorrhea
uterine contraction
source of ACTH
anterior pituitary basophils
type of ACTH
PROTEIN
ACTH stimulated by
stress
CRH
circadian rhythm
acth INHIITED BY
CORTISOL
Effects of ACTH
increased cortisol
increased androgens
maintains adrenal cortex
excess of ACTH
Cushing’s syndrome
deficiency of ACTH
Secondary Addison’s disease
