Nature

Striated means having thin lines, bands, grooves, or stripes on a surface.

Core meaning

In general English, something described as striated has a pattern of narrow, parallel lines or ridges, like striped rock layers or plowed fields. Many dictionaries define it simply as “marked with striations,” where striations are these small grooves or stripes.

Scientific and medical use

In biology and medicine, striated often refers to muscle tissue that looks striped under a microscope, such as skeletal and cardiac muscle. In geology, it can describe rocks or surfaces scratched or grooved by movement, for example by glaciers, giving them a lined appearance.
