The question in your minds about what is muscle tissue made up of.in histology you should know that muscle tissue is made up of fibers known as myocytes. The cytoplasm within the fibers
is called sarcoplasm, and within that sarcoplasm are minute myofibrils that contain the
protein filaments actin and myosin. These filaments slide past each other during a
muscle contraction, shortening the fiber.
Following are the three types of muscle tissue
Smooth muscle tissue: This type of tissue contracts without conscious control.
Made up of spindle-shaped fibers with large, centrally located nuclei, it’s found in
the walls of internal organs, or viscera. Smooth muscle gets its name from the
fact that, unlike other muscle tissue types, it is not striated.
Cardiac muscle tissue: Also known as myocardium, cardiac muscle tissue is
made of branching fibers, each with a central nucleus and alternating light and
dark striations. Between the fibers are dark structures called intercalated discs.
As with smooth muscle, cardiac muscle tissue contractions occur through the
autonomic nervous system.
Skeletal, or striated, muscle tissue: Biceps, triceps, pecs — these are the muscles
that bodybuilders focus on. As the name implies, skeletal muscles attach to
the skeleton and are used throughout the central nervous system for movement.
Muscle fibers are cylindrical with several nuclei in each cell (which makes them
multinucleated) and cross-striations throughout.
