Entero

Entero- is a prefix in both biology and medicine that originates from the Greek word ἔντερον (enteron), meaning "intestine." It typically serves to indicate a relation to the intestine.

Usage in Biology and Medicine

While the primary association of the prefix "entero-" is with the intestine, it can also refer to certain cells that may not be located directly within the intestine. Some of these cells are involved in endocrine functions and secrete various hormones in response to nutrient presence.

Key Examples

• Gastric enteroendocrine cells: These cells are found in the stomach and release different hormones like gastrin, which aids in the process of digestion.
• Pancreatic enteroendocrine cells: Located in the pancreas, these cells play a pivotal role in releasing hormones like insulin and glucagon to regulate blood sugar levels.
• Enterochromaffin cells: While most of these cells are found in the gastrointestinal tract, some are present in the lungs, brain, and other organs. They primarily produce and release serotonin.
