subscapular artery in dogs

The subscapular artery, the largest branch of the axillary artery, arises at the lower border of the Subscapularis, which it follows to the inferior angle of the scapula, where it anastomoses with the lateral thoracic and intercostal arteries and with the descending branch of the transverse cervical, and ends in the neighboring muscles. About 4 cm. from its origin it gives off two branches, first the scapular circumflex artery and then the thoracodorsal artery. [WP,unvetted].

The atlas records it as a artery at the organ scale in the dog.

Where the subscapular artery is

It sits within the cardiovascular system. Only the system is known. The position shown carries almost no spatial information.

What the subscapular artery connects to

The atlas records 3 typed relationships for it, across 2 kinds of connection. a kind of artery.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the subscapular artery. 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.
