MeSH definition : Cells that store epinephrine secretory vesicles. During times of stress, the nervous
system signals the vesicles to secrete their hormonal content. Their name derives
from their ability to stain a brownish color with chromic salts. Characteristically,
they are located in the adrenal medulla and paraganglia (PARAGANGLIA, CHROMAFFIN)
of the sympathetic nervous system.;
