What hormones do the ovaries produce
estrogen, progesterone, inhibin, and relaxin
When are inhibin and relaxin produced in women and what do they do
during pregnancy inhibin inhibits FSH and relaxin relaxes cartilage so pubic symphysis can widen during birth
What hormones do the testes produce
testosterone and inhibin
When do males produce inhibin
When sperm levels become too high, Inhibin inhibits/reduces spermatogenesis
Where is melatonin produced and when is it secreted the most
the pineal gland
-secreted more in darkness
What is melatonin though to do
setting the body’s biologic clock
What hormone does the atria of the heart produce and why
Atrial-natriuretic protein (ANP), produced when atria are stretched , aids in reduction of blood volume/pressure
What 3 hormones are produced in the kidneys and what do they do
- Renin=stimulates release of aldosterone
- Erythropoietin (EPO)=stimulates RBC synthesis
- Calcitriol=stimulates Ca absorption in the gut
What 2 hormones do adipose tissue produce and what do they do
- Leptin promotes satiety
2. Adiponectin= helps reduce insulin resistance
Name the hormones produced by the Thymus to promote T cell maturation
- Thymosin
- Thymic humoral factor
- Thymic factor
- Thymopoietin
What 4 hormones does the liver produce and what do they do
- IGFs
- Angiotensinogen= part of RAAS to raise BP
- Thrombopoietin= stimulates platelet production
- Hepcidin= block release pf iron into body fluids
Name 4 digestive tract hormones and there function
- Gastrin=promotes H secretion from parietal cells and stimulates growth of gastric mucosa
- Cholecystokinin (CCK)=stimulates gallbladder contraction and pancreatic enzyme release and slow gastric emptying
- Glucose dependent insulinotropic peptide=when food is in intestine triggers insulin release and inhibits H secretion by partial cells
- Secretin= secretion of pancreatic and billary bicarb and inhibits gastrin
Where are Eicosanoids found
all cells except RBCs
True or False Eicosanoids are local hormones
True, para and autocrine
What are 2 types of eicosanoids
Prostaglandins and Leukotrienes
Where is Histamine synthesized and how is it stimulated
- synthesized by mast cells and platelets
- stimulated by physical trauma to cells containing histamine
What is the function of Histamine
- contraction of smooth muscles
- dilate blood vessels
- stimulates gastric acid synthesis
- increases permeability of capillaries
Where is Serotonin synthesized
cells of the intestine, brain, CNS
True or False Serotonin is store in platelets
true
What are the 3 stress response stages
- Alarm phase= stress response starts
- adrenal cortex and sympathetic nervous symptom increased - The resistance phase=stressor is gone, but still dealing w/ psychologic aftermath,
- parasympathetic increases, sympathetic/steriods decreases - The exhaustion phase=stressor is not removed or the resistance phase was not sufficient enough
- depletion of physical and psychologic energy
- prolonged cortisol exposure and sympathetic stimulation
