What is another word for accompanying vein?
Pronunciation: [ɐkˈʌmpənɪɪŋ vˈe͡ɪn] (IPA) 
The term "accompanying vein" refers to a vein that runs parallel to another, larger vein. Synonyms for this term might include "companion vein," "parallel vein," "adjacent vein," or "sister vein." These terms all convey the same basic idea: that there is a smaller vein that is running alongside a larger one, providing support and drainage for the surrounding tissue. Depending on the context in which the term is used, some of these synonyms may be more appropriate than others. However, all of them can be useful for describing the anatomical structures of the human body or the veins within other organisms.
