pisiform in dogs

A laterally positioned sesamoid bone found in close proximity with and occasionally fused to the ulnare. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the pisiform is

A laterally positioned sesamoid bone found in close proximity with and occasionally fused to the ulnare. The atlas records it as a bone at the organ scale in the dog.

Where the pisiform is

It sits in the forelimb and forepaw, within the skeletal 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 pisiform connects to

The atlas records 8 typed relationships for it, across 3 kinds of connection. part of appendicular skeleton, manus and skeleton of manus.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the pisiform. 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 pisiform bone, accessory carpal bone and os pisiforme. Searching any of those names reaches this page.

Is the pisiform the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
