Pheochromocytoma produces symptoms of uncontrolled sympathetic nervous system activity. is common to both adrenal chromaffin cells and adrenergic fibers of the sympathetic nervous system.

Norepinephrine.

Explanation:

According to my research on studies conducted by various neurologists, I can say that based on the information provided within the question the term being described is called Norepinephrine. This is a neurotransmitter secreted by neurons in the sympathetic nervous system. This chemical is secreted in response to stress, which triggers the 'fight or flight response.' Which is basically the main triggers in Adrenaline within the sympathetic nervous system.

I hope this answered your question. If you have any more questions feel free to ask away at .

uh two lol

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
