This time, each magnet is now attracted to the iron plate, and don't see the other magnet on the other side of the plate, even though both of the North poles are facing each other! The diagram on the right shows what happens if you insert a superconductor between the magnets. Now, each magnet is repelled by the superconductor, and there is little or no attraction between the magnets themselves (one little field line did sneak around the superconducting plate, though).
Cardiac muscle (heart muscle) This type of muscle is found solely in the walls of the heart. It has similarities with skeletal muscles in that it is striated and with smooth muscles in that its contractions are not under conscious control. However this type of muscle is highly specialised.
3 Types of Muscle Tissue: The Function of Skeletal, Cardiac, and Smooth Muscle. About half of your bodyâs weight is muscle. In the muscular system, muscle tissue is categorized into three distinct types: skeletal, cardiac, and smooth. Each type of muscle tissue in the human body has a unique structure and a specific role. Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions. Here are more details about the structure and function of each type of muscle tissue in the human muscular system.
