Function[edit | edit source]
They produce and contain about 90% of the body's store of serotonin (5-HT).
In the gastrointestinal tract, 5-HT is important in response to chemical, mechanical or pathological stimuli in the lumen. It activates both secretory and peristaltic reflexes, and activates vagal afferents (via 5-HT3 receptors) that signal to the brain (important in the generation of nausea).
Etymology[edit | edit source]
"Enterochromaffin-like cells"[edit | edit source]
Another population of chromaffin cells is found only in the stomach wall, called enterochromaffin-like cells (ECL). They look "like" EC cells but do not contain 5-HT.
