metacarpal bone of digit 1 in dogs

A metacarpal bone that distally_connected_to a proximal phalanx of manual digit 1. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the metacarpal bone of digit 1 is

A metacarpal bone that distally_connected_to a proximal phalanx of manual digit 1. The atlas records it as a bone at the organ scale in the dog.

Where the metacarpal bone of digit 1 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 metacarpal bone of digit 1 connects to

The atlas records 25 typed relationships for it, across 6 kinds of connection. part of anatomical structure, anatomical system and appendage, and 15 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the metacarpal bone of digit 1. 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.
