This section of notes provides an overview mainly of adult pancreas histology, see also Pancreas Development notes.
Page also provides further histology background information for Medicine phase 1 Health Maintenance B Practical 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.
