Cardiac and skeletal muscle both possess striations. True False

True! Both cardiac and skeletal muscle fibers exhibit distinct striations, making them visually similar under a microscope. These striations are due to the organized arrangement of sarcomeres, the basic contractile units of muscle. While they share this characteristic, cardiac muscle is unique in that it is involuntary and interconnected through intercalated discs, allowing for coordinated contractions. However, don't forget that cardiac muscle is an endurance champ! It continuously works to pump blood throughout your life, while skeletal muscle is all about movement and strength. So, whether you're flexing those biceps or your heart's beating strong, both types of muscle are pretty amazing in their own ways!
