 Hello Thor,
the provided links I and Willem have posted don't tell something about "dots in a row" but confirm this with other words. very clear in this link: 
http://www.internationalivorysociety...y-bob-weisblut like follow: 
"There is a nerve root that looks like a "dash" or curved line properly referred to as a "TIZ". "
And sometimes a picture can tell much more as written words. The picture is taken from here:
