X-rays are waves of electromagnetic radiation that are absorbed differently by different tissues. Bones absorb them well because they are dense. A skeletal X-ray specifically looks at your skeletonâwhich is made up of all the bones in your body.
Cross section of a skeletal muscle (200x) showing the muscle fibers (red) and the fat cells (white) Skeletal muscle is also called striated muscle, because when it is viewed under polarized light or stained with an indicator, you can see alternating stripes of light and dark. Skeletal muscle has a complex structure that is essential to how it contracts. We will tease apart a skeletal muscle, starting with the largest structures and working our way to the smaller ones.
