6.2 Physiology of the Endocrine System Part 4 Flashcards
What is the response caused by the release of epinephrine and norepinephrine?
“fight or flight”
rise in blood glucose levels
increase in metabolic rate
increase in breathing rate
increase in heart rate
What do the blood vessels in the intestine and muscles do in reponse to the release of epinephrine and norepinphrine?
intestine = constrict
muscles = dilate
What is epinephrine used for as an emergency drug?
stimulate the patients body during cardiac arrest
What else can help initiate the fight or flight response besides epinephrine and norepinephrine?
sympathetic nervous system
Which part of the adrenal gland is essential for life?
adrenal cortex
What are the two classes of hormones made by the adrenal cortex?
glucocorticoids
mineralcorticoids
Which part of the adrenal glands secretes male and female sex hormones?
adrenal cortex
What type of hormone is cortisol classified as?
glucocorticoid
What controls the secretion of cortisol from the adrenl cortex?
anterior pituitary hormone ACTH
What is the function of cortisol?
promotes hydrolysis of muscle protein to amino acids that enter the blood and get converted to glucose by the liver
What does cortisol favor for metabolism: fatty acids or carbohydrates?
fatty acids
What is the final action of the release of cortisol?
rise in blood glucose levels
Which hormone released by the adrenal cortex counteracts the inflammatory reponse?
cortisol
What hormone would be administered to help release the body experiencing pain and swelling?
cortisol
What classification of hormone is aldosterone?
mineralcorticoids
