pancreatic acinus

The secretory units of the exocrine pancreas, where fluid containing digestive enzymes is produced; consists of a group of secretory cells surrounding a luminal space that connects to the pancreatic duct. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the pancreatic acinus is

The secretory units of the exocrine pancreas, where fluid containing digestive enzymes is produced; consists of a group of secretory cells surrounding a luminal space that connects to the pancreatic duct. The atlas records it as a gland at the organ scale in the human body.

Where the pancreatic acinus is

It sits in the trunk, within the digestive system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the pancreatic acinus connects to

The atlas records 4 typed relationships for it, across 3 kinds of connection. part of exocrine pancreas and pancreatic lobule.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the pancreatic acinus. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as acinus pancreaticus, pancreas acinus, pancreatic acinar and pancreatic acini. Searching any of those names reaches this page.

Questions

Where is the pancreatic acinus?

It sits in the trunk, within the digestive system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What does the pancreatic acinus connect to?

Part of: exocrine pancreas and pancreatic lobule.

Is the pancreatic acinus the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
