Learn English – What are these lines depicting movement in a cartoon called

From Wikipedia...

In comics, motion lines (also known as movement lines, action lines, speed lines, hites or zip ribbons) are the abstract lines that appear behind a moving object or person, parallel to its direction of movement, to make it appear as if it is moving quickly.

I can't find a corresponding (domain-specific?) definition of abstract lines as used above, but I'm guessing it's intended to imply lines which convey an abstract quality such as movement, emotion, etc. - rather than something "material", such as might be captured by a photographic image.

By implication therefore, exclamation marks or a lightbulb drawn above a cartoon character's head (indicating surprise, or a sudden inspiration) ought to also be called "abstract" lines / glyphs / punctuation marks, but I've never come across any such usage myself.

For anyone who thinks this is "Quiite Interesting" (such as me, now my attention is focused on it), I also found this post on Pinterest...

Hites, Vites, Dites, or Briffits.

Hites are horizontal lines to indicate speed or movement. Vites are vertical lines that add shine on a floor or an icy pond. Dites are diagonal lines to represent the reflection in a window or mirror. And Briffits are simply cloud-shaped dust clouds.

Fascinating stuff, domain-specific terminology.
