Function and location of somatostatin

pancreas delta cells | inhibits insulin and glucogon secretion

Function and location of cortisol

adrenal cortex antagonize effects of insulin inhibit inflammatory response inhibits fibroblastic activity

Function and location of aldosterone

adrenal cortex | promotes retention of Na+

Function and location of androgens and estrogens

adrenal cortex | development of secondary sexual characteristics

Function and location of epinephrine and norepinephrine

adrenal medulla | regulate BP by effects on vascular smooth muscle and heart

Effects of catecholamines on the brain

increased blood flow | increased glucose metabolism

Effects of catecholamines on the cardiovascular system

increased rate and force of contraction | peripheral vasoconstriction

Effects of catecholamines on the pulmonary system

increased oxygen supply bronchodilation increased ventilation

Effects of catecholamines on the muscle

increased glycogenolysis increased contraction increased dilation of skeletal muscle vasculature

Effects of catecholamines on the Liver

increased glucose production | increased gluconeogene

Effects of catecholamines on adipose tissue

increased lipolysis | increased fatty acid and glycerol

Effects of catecholamines on the skin

decreased blood flow

Effects of catecholamines on the skeleton

decreased glucose uptake and utilization | decreased insulin release

Effects of catecholamines on the GI tract

decreased protein synthesis

Effects of catecholamines on the lymphoid tissue

increased protein breakdown

What hormones act as intracellular receptors

Nonpolar hormones

What hormones act as extracellular receptors

Polar hormones

hormones that circulate freely are _____

Polar hormones

What type of hormone needs carrier proteins

Nonpolar hormones

Down regulation is

decreased cell receptors due to increase of the amount of circulating hormones

Up regulation is

increased cell receptors due to decrease of the amount of circulating hormones

Function and location of melatonin

Pineal gland | Regulates circadian rhythms
