During a lab practical, Kevin examines a tissue that is composed of densely packed protein fibers that are running parallel and form a cord. There are few nuclei and no striations, and there is no evidence of other cellular structures. Kevin identifies the tissue as skeletal muscle. Why is Kevin's choice wrong, and what tissue is he probably observing?
What will be an ideal response?
Skeletal muscle tissue is made up of densely packed fibers running in the same direction, but since muscle fibers are composed of cells, they would have many nuclei and mitochondria. Skeletal muscle also has an obvious banding pattern or striations due to the arrangement of the actin and myosin filaments within the cell. Kevin is probably looking at a slide of tendon (dense connective tissue).
