Which of the following muscle tissues are striated? Cardiac muscle Skeletal muscle All of these Smooth muscle Cardiac and Skeletal muscle

Did you know that both cardiac and skeletal muscles have those classic stripes we call striations? These striations come from the organized structure of the myofibrils within the muscle fibers, making them super efficient at contracting quickly and powerfully. This design is crucial for skeletal movements and the rhythmic beating of your heart! In contrast, smooth muscle lacks these striations and is mostly found in the walls of hollow organs. Think of your intestines or blood vessels where smooth muscle works tirelessly, contracting slowly and involuntarily to keep things moving smoothly along without the flash and dash of striated muscles. It's like the quiet hero of bodily functions!
