    Cardiac muscle is striated, involuntary muscle found in the heart wall. Cardiac muscle cells contain the same contractile filaments as in skeletal muscle. Smooth muscle is non-striated, involuntary muscle found in many locations. Smooth muscle cells are spindle-shaped with a centrally located nucleus. Skeletal muscle cells are filled with tightly packed myofibrils. Myofibrils show an alternating series of striations due to the repeating sarcomeres.

    • Muscular tissue is a specialized tissue in animals which applies forces to different parts of the body by contraction. It is made up of thin and elongated cells called muscle fibers. It controls the movement of an organism. The cytoplasm in the muscle fibers is called sarcoplasm. It contains a network of membrane called the sarcoplasmic reticulum. The membrane surrounding the muscle fibers is called sarcolemma. The muscular tissues are bundled together and surrounded by a tough connective tissue similar to cartilage known as epimysium. The bundle of nerve cells that run in long fibers called fascicles are surrounded by the epimysium. The fascicles are surrounded by a protective layer known as perimysium. It allows the flow of nerves and blood to the individual fibers. Another protective layer, the endomysium surrounds the fibers. These layers and muscles help in the contraction of different parts of the muscles. The different bundles slide past one another as they contract. The epimysium connects to the tendons attached to the periosteum connective tissue that surrounds the bones. This helps in the movement of the skeleton when the muscles contract. The epimysium connects to other connective tissues to produce a force on the organs and control everything from circulation to food processing. The muscular tissue is of three types: Skeletal Muscle Tissue, Smooth Muscle Tissue, and Cardiac Muscle Tissue.
