Talk:vasa vasorum

Singular

Vasa vasorum is stipulated to be already plural, meaning literally "the [little] vessels of the [big] vessels". How about singular?

According to the Wiktionary etymology, and with reference to the table of declensions for the Latin root word vas (I'm not a native speaker of Latin!), I suppose that there are two logical and anatomically relevant options:

• vasa vasis = "the [little] vessels of a [big] vessel", for instance the little blood vessels that supply the aorta;
• vas vasis = "a [little] vessel of a [big] vessel", for instance one of the little blood vessels that supply the aorta.

Neither of the above singular forms appears to be in common use. But examples do appear in the literature.

• Examples of "vasa vasis": "Vasa vasis of the ascendens aorta" [1]; " the testicular vein and vasa vasis" [2]
• Example of "vas vasis": "a newly innervated arterial vas vasis of the vein" [3].
