Noun. 1. striation-any of a number of tiny parallel grooves such as: the scratches left by a glacier on rocks or the streaks or ridges in muscle tissue. stria. groove, channel-a long narrow furrow cut either by a natural process (such as erosion) or by a tool (as e.g. a groove in a phonograph record).
The A and I bands repeat along the length of the muscle fibers to create the striations visible under the light microscope. 1  Sarcomeres repeat along skeletal and cardiac fibers. 2  Components between adjacent Z-lines comprise the sarcomere. 3  Sarcomeres are considered the functional units of striated muscles.n views of this muscle type, striations are not as strong as those of skeletal muscle. Other structural features are usually apparent and of use for identification if the striations are weak. Due to constant activity cardiac muscle has a constant need for oxygen and glucose delivery.
