Endocrine System: Response to Stress

STUDY
PLAY
Nervous System and Endocrine System
What two body systems work together to provide well coordinated, generalized, nonspecific responses to combat stress?
epinephrine, norepinephrine, and cortisol
Increased levels of what three hormones indicate that an individual is experiencing stress? E,N, and C
Ephinephrine and Norepinephrine
In the nervous system's response to stress, ______ and _____________ exert many effects on the body.
Increased (CO, Ventilation, BP, Sweating, and Plasma Levels)
Decreased (Insulin and blood flow to digestive system)
ACTh
In response to stress, the hypothalamus increases the release of CRH, which increases ________ from the anterior pituitary and __cortisol_________ from the adrenal cortex. These hormones prolong the response to stress provided by the nervous system.
Cortisol
In response to stress, the hypothalamus increases the release of CRH, which increases _ACTh_______ from the anterior pituitary and ___________ from the adrenal cortex. These hormones prolong the response to stress provided by the nervous system.
Vasoconstriction
Cortisol enhances ____________________ (in vessels) to help maintain blood pressure and also (inhibits) the inflammation and immune response.
Inhibits
Cortisol enhances ___vasoconstriction_________________ (in vessels) to help maintain blood pressure and also (inhibits or increases) the inflammation and immune response.
Aldosterone
Besides cortisol, the adrenal cortex releases _______________, which promotes salt and water retention, which helps maintain blood volume and blood pressure
Vasopressin
____________ (posterior pituitary hormone) also aids in the stress response by promoting water retention and at high levels it is a potent ____vasoconstrictor___________. Both of these help maintain blood pressure.
Vasoconstrictor
___Vasoporessin_________ (posterior pituitary hormone) also aids in the stress response by promoting water retention and at high levels it is a potent _______________. Both of these help maintain blood pressure.
Hydrophilic
Epinephrine is a (hydrophilic or lipophilic) hormone. Thus it( does not) require a protein carrier and the receptors at the target cell are located _on the membrane______________.
Does not
Epinephrine is a (hydrophilic) hormone. Thus it(does or does not) require a protein carrier and the receptors at the target cell are located _on the membrane______________.
on the membrane
Epinephrine is a (hydrophilic) hormone. Thus it( does not) require a protein carrier and the receptors at the target cell are located _____________.
Tyrosine
Epinephrine is synthesized from _____________ and has a very short half-life of __10 seconds____.
10 Seconds
Epinephrine is synthesized from ____tyrosine__________ and has a very short half-life of __..... __ seconds.
Pheochromocytoma
___________ is a condition in which there is hypersecretion of catecholamines by a tumor in the adrenal medulla.
A patient with this condition would display these symptoms:
-sweating
-increased BP, Blood Glucose, HR, TPR
Lipophilic
Cortisol is a (lipophilic or hydrophilic) hormone. Thus it (does) require a protein carrier and the receptors on the target organ are located ___inside the cell__________. Cortisol is synthesized from ___cholesterol__________ and has a half-life of __90 minutes_______.
Does
Cortisol is a (lipophilic) hormone. Thus it (does or does not) require a protein carrier and the receptors on the target organ are located ___inside the cell__________. Cortisol is synthesized from ___cholesterol__________ and has a half-life of __90 minutes_______.
inside the cell
Cortisol is a (lipophilic) hormone. Thus it (does) require a protein carrier and the receptors on the target organ are located _____________. Cortisol is synthesized from ___cholesterol__________ and has a half-life of __90 minutes_______.
