penicillar arteriole

One of the small straight arteries of the red pulp of the spleen; a branch of the spleen central artery that supplies the red pulp[WP,modified]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the penicillar arteriole is

One of the small straight arteries of the red pulp of the spleen; a branch of the spleen central artery that supplies the red pulp[WP,modified]. The atlas records it as a organ at the organ scale in the human body.

Where the penicillar arteriole is

It sits in the abdomen and trunk, within the cardiovascular and lymphatic & immune systems. 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 penicillar arteriole connects to

The atlas records 8 typed relationships for it, across 3 kinds of connection. part of abdomen, abdominal segment of trunk and spleen, and 2 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the penicillar arteriole. 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.
