    Study Notes

    Characteristics of Muscle Tissue

    • Muscle tissue cells have the special ability to shorten or contract, producing movement of body parts
    • Muscle tissue is highly cellular and well supplied with blood vessels
    • The contractile proteins in muscle tissue are actin and myosin
    • The cytoplasm in muscle fibers is called sarcoplasm, which contains a network of membrane called the sarcoplasmic reticulum
    • The membrane surrounding muscle fibers is called sarcolemma

    Types of Muscle Tissue

    • There are three main categories of muscle tissue: skeletal, smooth, and cardiac
    • Skeletal muscle tissue is also referred to as striated muscle tissue
