|
TSH
|
Thyroid Stimulating Hormone
|
|
|
PRL abnormalities
|
Hyposecretion-
cretinism (child) Myxedema (adults) if iodine deficient --> Goiter Hypersecretion - Graves Disease (Mrs. Bush!) Sign- Exopthalmos |
|
|
GH abnormalities
|
Hypersecretion: Gigantism (child) Acromegaly (adult)

|
|
TSH main effects
|
develop, secretion of thyroid hormone
|
|
|
GH effects
|
Effects (anabolic)
increased AA uptake (muscle) increased sulfur into cartilage matrix Fat released into blood (inhibits adipose synthesis Decreased glucose use by cells (anti-insulin action) |
|
|
TSH abnormalities
|
Hyposecretion-
cretinism (child) Myxedema (adults) if iodine deficient --> Goiter Hypersecretion - Graves Disease (Mrs. Bush!) Sign- Exopthalmos |

|
LH/FSH features
|
released at puberty
stimulated by gonadotropin releasing hormone (hypothalamus) exhibits feedback inhibition found both in males & females |
|
|
ADH info
|
inhibits urine production by kidney
stimulus is osmoreceptors high [solute] in blood + --> ADH release hypersecretion rare inhibition (-) of ADH (alcohol, diuretics) Diabetes insipidus (polyuria, polydipsia) |
