periarterial lymphatic sheath in dogs

The area of the spleen in which T cells surround the central arteriole. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the periarterial lymphatic sheath is

The area of the spleen in which T cells surround the central arteriole. The atlas records it as a organ at the organ scale in the dog.

Where the periarterial lymphatic sheath is

It sits in the abdomen and trunk, within the lymphatic & immune system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What the periarterial lymphatic sheath connects to

The atlas records 8 typed relationships for it, across 3 kinds of connection. part of lymphoid system and white pulp of spleen.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the periarterial lymphatic sheath. 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.
