adrenocorticotropic hormone

triggers the release of glucocorticoids by the suprarenal cortex.

follicle stimulating hormone

stimulates follicle development and estrogen secretion in females and sperm production in males

calcitriol

stimulates calcium and phosphate ion absorption along the digestive tract

erythropoietin

stimulates red blood cell production by the bone marrow

FSH production in males supports

maturation of sperm by stimulating nurse cells

ADH and oxytocin are hormones release by

neurohypophysis

cells hormone sensitivities are determined by the

presence or absence of appropriate receptors

paracrine

use of a chemical messenger to transfer information from cell to cell within a single tissue is referred to as _________ communication

alpha cells

glucagon

beta cells

insulin

delta cells

somatostatin

F cells

pancreatic polypeptide

what makes up the endocrine pancreas?

alpha, beta, delta, F cells

Increased blood calcium levels would result in increased

secretion of calcitonin

growth is affected by

growth hormone, thyroid hormones, insulin, parathyroid hormone, calcitriol, and reproductive hormones

cells of endocrine pancreas from clusters called

pancreatic islets (islets of Langerhans)

C cells of the thyroid follicles produce

calcitonin (CT) which help to regulate Ca+2 concentrations in body fluids, especially during childhood and pregnancy

thymus produces a hormone called

thymosins, which play a role in developing and maintaining normal immune defenses

General Adaptation syndrome (GAS)

alarm phase, resistance phase, and exhaustion phase

alarm phase

immediate flight or fight response under direction of the sympathetic division of the ANS

resistance phase

dominated by glucocorticoids

exhaustion phase

eventual breakdown of homeostatic regulation and failure of one or more organ systems

kidneys produce the hormones

calcitriol and erythtoprotein and the enzyme renin

insulin lowers blood glucose by increasing

the rate of glucose uptake and utilization'

glucagon raises blood sugar by

increasing the rates of glycogen breakdown and glucose manufacture in the liver
