Study Notes
###Â Parenchyma Structure
- Composed of lobules
- Lobules are separated by connective tissue septa.
- Lobules form the functional unit of the gland and contain acini (secretory units) and ducts.
###Â Secretory Unit
- Consists of cells with a pyramidal shape, broad base, and a narrow apical surface
- Cells have a round central nucleus, well-stained rough endoplasmic reticulum, and basophilic cytoplasm.
- Cells are connected by junctional complexes.
- Form a rounded secretory unit called an acinus, with a small lumen
- Â Apical zymogen granules present for protein secretion
###Â Intralobular Duct System
- Secretory acini and tubules empty into intercalated ducts.
- Intercalated ducts are the smallest branches with a small diameter
###Â Â Pancreas Histological Structure
- Â Stroma
- A capsule of connective tissue surrounds the pancreas. -Â Connective tissue septa divide the pancreas into lobules.
