Term
addisons
Definition
in this disease, signs and symptoms are due to decreased levels of aldosterone and cortisol, excersive pigmentation, anorexia, nausea, diarrhoea and vomitting, and mental confusion, decreased ability to withstand stress, dehydration, hypotnesion and loss of weight
Term
congenital adrenal hyperplasia
Definition
in this condition, it is mostly due to a lack of 21 Beta hydroxylase and hyperplasia is due to an increase in secretion of ACTH and the signs and symptomos are due to an increase in secretion of DHEA
Term
adreno genital syndrome
Definition
in this syndrome, it is caused by excessive secretion of DHEA, women will develop male secondary characteristics, deeping voice, amenorrhoea, enlarged clitoris, hair growth, and an increase in muscle mass
Term
Conn's
Definition
in this syndrome, due primarily to hyperaldosteronism; hypertension, hypernatremic, hypokalemic, person will suffer from alkalosis, muscle weakness, fatigue and paralysis, tetany, polyuria
Term
noradrenaline
Definition
Peripheral resistance is the factor that is responsible for the diastolic BP. ____ is a powerful vasoconstrictor
Term
dilation
Definition
what effect does noradrenaline have on iris
Term
phaeochromocytoma
Definition
this condition is caused because there is a tumor in the adrenal medulla, there will be an abnormally high amount of secretion of hormones from adrenal medullary region and some of the features; sustained hypertension, palpitation, sweating, headache, hyperpnoea, nausea and vomiting, anxiety and muscualr weakness
Term
acini

Term
chief cells
Definition
what type of cells are responsible for the secrection of PTH?
Term
calcium; phosphate
Definition
PTH in the kidney increases ___ reabsorption from the DCT and decreases ___ resabsorption from the PCT
Term
