chromaffin वाक्य

Chromaffin cells of the adrenal medulla are analogous to post-ganglionic neurons; the adrenal medulla develops in tandem with the sympathetic nervous system and acts as a modified sympathetic ganglion.
The largest chromaffin paraganglia is the organ of Zuckerkandl, it is probably the largest source of circulating catecholamines in the fetus and young infants, and gradually atrophies to microscopic loci.
Composed mainly of hormone-producing chromaffin cells, the adrenal medulla is the principal site of the conversion of the amino acid tyrosine into the catecholamines epinephrine, norepinephrine, and dopamine.
enterochromaffin-like cells, both being enteroendocrine cells, are also considered neuroendocrine cells due to their structural and functional similarity to chromaffin cells, although they are not derivatives of the neural crest.
are the two main types of cells of the renal medulla the chromaffin and postganglionic cell ? anyone know where to get more information on this, seems the wiki article doesn't mention much.

While PNMT is found primarily in the cytosol of the endocrine cells of the adrenal medulla ( also known as chromaffin cells ), it has been detected at low levels in both the heart and brain.
The adrenal medulla produces adrenomedullary hormones in chromaffin cells, cells which are very similar in structure to post-synaptic sympathetic neurons, even though they are not neurons they are derivatives of the neural crest.
In non-mammals, chromaffin cells are found in a variety of places, generally not organized as an individual organ, and may be without innervation, relying only on endocrine or paracrine signals for secretion.
In the categorization proposed by Wick, paragangliomas belong to group II . Given the fact that they originate from cells of the orthosympathetic system, paragangliomas are closely related to pheochromocytomas, which however are chromaffin-positive.
The enterochromaffin cells are so named because of their histological similarity to chromaffin cells ( they also stain yellow when treated with chromium salts ), but their function is quite different and they are not derivatives of the neural crest.
