The anterior of the pituitary gland produces what?
GH, ACTH, FSH, LH TSH
Posterior of the pituitary gland does what?
Storage, of hormones, oxytocin and ADh
Adrenal cortex produces what?
Corticosteroids, androgens and aldosterone
Adrenal medulla produces what?
catecholamines
Primary oversecretion is a problem with what?
The gland itself
Secondary oversecretion problem?
Pituitary
Tertiary oversecretion is a problem with?
Hypothalamus
What are static tests?
Simple measurements at a moment in time such a TSH and T3/4
Pirmary hyperthyroidism would give what results?
high T3/4 suppressed TSh
Stimulation tests used in what conditions?
Under secretion such as adrenal insufficency
Giving ACTH for adrenal insufficiency
synacthen test
What is the gold standard for diagnosing pituitary insufficiencey
Insulin stress test
Growth hormone oversecretion can be tested by supression using What?
Glucose
Excess steroid secretion can be tested for by doing what?
Giving external hormones which can be independent measured.
Prolactinoma symptoms?
Pituitary tumour secreting prolactin, glactorrhoea, amennorhea, sexual dysfunction, headaches
What condition can be observed in adult patients with over secretion of GH?
Acromegaly
Primary Cushings syndrome is what?
adrenal tumour secreting cortisol
Secondary Cushings is due to?
Pituitary secreting too much ACTH
Most common cause of overactive thyroid?
Graves disease (autoimmune)
Drug induce overactive thyroid caused by?
Amiodarone
Drugs used for supression of overactive thyroid =
radioactive iodine and carbimazole
Insulin stress test for Gh deficiency causes what to happen?
Stress on body and Gh should rise
Gnrh controls what and from where?
Gonadotrophin releasing hormone, from hypothalamus
What does the pituitary not control!?
Pancreas, parathyroid and adrenal medulla (mineralocorticosteroids)
