| Name: | pancreas |
|---|---|
| Synonyms: | |
| Definition: | The pancreas is an organ composed of endocrine and exocrine glandular tissue that produce hormones and digestive enzymes. Unlike in other studied vertebrates the pancreas in zebrafish develops from two buds, one anterior and one posterior. In adult fish the main pancreas is located on the right side attached to the lateral aspect of the intestine by the pancreatic duct. Typically, one large islet and 3-6 smaller islets occupy the main pancreas. The tail of the pancreas is embedded with single beta cells or clusters of small islets and extends caudally along the right side of the intestine. |

| Name: | endoplasmic reticulum |
|---|---|
| Synonyms: | ER |
| Definition: | The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached). |
