Physiology Flashcards
Pineal Gland aka
Epithalamus
Neurohypophysis aka
posterior pituitary
Adenohypophysis aka
anterior pituitary
embryology of ant pit
rathke’s pouch
embryology of post pit
diencephalon
ant pit hormones
ACTH FSH GH LH MSH Prolactin TSH (all the stimulators)
post pit hormones
ADH/vasopressin
oxytocin
lack of ADH gives
diabetes insipidus
surface ectoderm aka
oralectoderm (rathke’s pouch of ant pit)
when are cortisol levels high
not eating - morning
or stress
cushing’s
hyperadrenalism = hypercortisolism
purple, buffalo hump, moon
addison’s
low bp
hypoadrenalism = hypocortisolism
hyperpig mouth and face
prolactin must be inhibited by ___ to stop positive feedback
dopamine
how does the thyroid get its iodine
iodine pump
thyrotoxicosis
aka hyperthyroidism
GH aka
somatropin
GH is a carb
sparer - burns fats not carbs
somatomedin
from liver mediates GH for cartilage
MSH
basement layer of epidermis, stim by UV light
TSH found in
thyroid follicular cells
TSH
T4, T3 (made from T4- called triiodothryonine)
which is stronger T3 or T4
T3
PTH aka Parathormone does what
takes Ca out of bone and into blood
decreases phosphourous
increases calcium absorption in intestine
calcitonin produced where
parafollicular cells of thyroid
calcitonin does what
pulls calcium out of blood and into bone
hyperparathyroidism
brown’s tumor, rugger jersey spine
adrenal cortex is a derivative of
mesoderm
GFR zones
adrenal medulla derived from
neural crest cells
Glomerulosa
Fasiculata
Reticularis
Aldosterone - mineral corticois salt
Cortisol - glucocorticoid sugar
Sex Hormones - sex
excess aldosterone causes
conn’s syndrome, hypertension retain water
adrenal medulla has chromaffin cells that secrete
NE and E = incr blood sugar
tumor of adrenal medulla is called
pheochromocytoma
