Chromaffin Cell Imaged With DIC And IRM
Taking up and staining strongly with Chromium salts. Chromaffin may refer to: *Chromaffin cells, neuroendocrine cells in the adrenal medulla. *Chromophil A chromophil biological cell is a cell which is easily stainable by absorbing chromium salts used in histology to increase the visual contrast of samples for microscopy. Function Chromophil cells are mostly hormone-producing cells containing so-c ...

Chromaffin Cells
Chromaffin cells, also called pheochromocytes (or phaeochromocytes), are neuroendocrine cells found mostly in the medulla of the adrenal glands in mammals. These cells serve a variety of functions such as serving as a response to stress, monitoring carbon dioxide and oxygen concentrations in the body, maintenance of respiration and the regulation of blood pressure. They are in close proximity to pre-synaptic sympathetic ganglia of the sympathetic nervous system, with which they communicate, and structurally they are similar to post-synaptic sympathetic neurons. In order to activate chromaffin cells, the splanchnic nerve of the sympathetic nervous system releases acetylcholine, which then binds to nicotinic acetylcholine receptors on the adrenal medulla. This causes the release of catecholamines. The chromaffin cells release catecholamines: ~80% of adrenaline (epinephrine) and ~20% of noradrenaline (norepinephrine) into systemic circulation for systemic effects on multiple organs ...
