ANATOMY

Detailed explanation-1: -The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control.

Detailed explanation-2: -Cardiac muscle tissue, like skeletal muscle tissue, looks striated or striped. The bundles are branched, like a tree, but connected at both ends. Unlike skeletal muscle tissue, the contraction of cardiac muscle tissue is usually not under conscious control, so it is called involuntary.

Detailed explanation-3: -Cardiac muscle is characterized as striated muscle because microscopically, it presents a striated appearance essentially identical to that of skeletal muscle; it also shares with skeletal muscle many similar ultrastructural features.

Detailed explanation-4: -Skeletal muscle fibers are red and white. They look striated, or striped, so they’re often called striated muscles. Cardiac muscles are also striated, but smooth muscles aren’t.

Detailed explanation-5: -Striation: Muscle tissue in which the contractile fibrils in the cells are aligned in parallel bundles, so that their different regions form stripes visible in a microscope. Cardiac muscle (myocardium): Involuntary, striated muscle that constitutes the main tissue of the walls of the heart.
