Gastrointestinal Tract - Pancreas Histology
This section of notes provides an overview mainly of adult pancreas histology, see also Pancreas Development notes.Virtual Slides. This page content is not part of the HMB practical class.
- exocrine pancreas consists of tubuloacinar glands.
- single layer of pyramidal shaped cells forms the secretory acini (cells contain zymogen granules).
- Secretory duct pathway:
- Intercalated Duct
- Intralobular Duct (low columnar or cuboidal epithelium, non-striated)
- Interlobular Duct (columnar epithelium + goblet cells)
- Main Pancreatic Duct

The pancreatic islets (Islets of Langerhans) contain four distinct endocrine cell types.
