If epinephrine and norepinephrine cause dilation, are they stimulating or inhibiting? Please explain.
ANSWER :
Sympathetic division of autonomic nervous system stimulate the dilation of pupil via releasing the epinephrine and norepinephrine (catecholamines) from the adrenal medulla, also perform their stimulatory function during the fight, fright and flight conditions.
If epinephrine and norepinephrine cause dilation, are they stimulating or inhibiting? Please explain.
Epinephrine: disrupts release of norepinephrine by brainstem nuclei. is released by the basolateral nucleus in response to foot shock. crosses the blood-brain barrier to directly influence the amygdala. activates brainstem nuclei that produce norepinephrine from epinephrine.
Adrenal medulla: release of Epinephrine and Norepinephrine A. Where are they made? (cells, organ) B. What organ/or cells secrete them? (may differ from site of formation) C. What stimulates their secretion? Explain negative feedback control of secretion. Where do they work (target)? E. What do they regulate: physiological outcome?
How does glucocorticoid vs epinephrine/norepinephrine release impact us differently (this could be with regards to mood, appetite, etc.)?
S-adenosylmethionine (SAM, top structure) reacts with norepinephrine (bottom structure) to form epinephrine. Draw curved arrows to show how this reaction proceeds. The first curved arrow is drawn for you–a basic amino acid side chain (B) is positioned in the active site to deprotonate the amine.

Labetalol, a β-blocker antagonist of epinephrine and norepinephrine is commonly used in treating high blood pressure. Labetalol can be synthesized from a primary amine and an epoxide. Using the starting materials below, add curved arrows to complete the mechanism for the synthesis of Labetalol. The general base (:B) will be used for proton transfers.
