On rocks - they are the parallel groves or scratches.
Or on skeletal or cardiac muscle: they are the "strands" of the muscle.
striations
Yes they have Cross Striations
Striations are light and dark bands on skeletal and caridac muscle fibers. Smooth muscle lacks striations
The marble was smokey grey with black and white striations.
A sodium feldspar with twinning striations is called albite, while a calcium feldspar with twinning striations is called anorthite.
They are called striations.
Cross-striations form cardiac muscle. The crossed formation makes the tissue and muscle stronger.
Kyanite is a silicate mineral that is characterized by its striations on the crystal faces. These striations are fine grooves or ridges that run parallel to the crystal's length and help differentiate kyanite from other minerals.
Minerals that exhibit striations include feldspar, particularly plagioclase, and quartz. Striations are fine, parallel lines or grooves found on the crystal surfaces of these minerals, often resulting from their crystallization processes. Other minerals, such as calcite and some varieties of pyroxene, can also show striations, which can be important for identification in mineralogy.
Striations in the human body are primarily seen in skeletal muscle tissue and cardiac muscle tissue. In skeletal muscles, these striations appear as alternating light and dark bands due to the arrangement of actin and myosin filaments, which facilitate voluntary movement. In cardiac muscle, striations are also present, but the muscle fibers are interconnected, allowing for coordinated contractions of the heart. Smooth muscle, in contrast, does not exhibit striations.
Fudge ripple ice cream is vanilla with striations of fudge through it.
