Types of muscle tissues.

1. Skeletal muscle tissue: This type of muscle tissue is attached to bones and is responsible for voluntary movements of the body. It is striated in appearance and is under conscious control.

2. Cardiac muscle tissue: Found only in the heart, cardiac muscle tissue is responsible for pumping blood throughout the body. It is striated like skeletal muscle but is involuntary, meaning it contracts without conscious control.

3. Smooth muscle tissue: Smooth muscle tissue is found in the walls of hollow organs such as the intestines, blood vessels, and bladder. It is non-striated and involuntary, controlling functions such as digestion, blood flow, and urination.

1. Skeletal Muscle Tissue

- Attached to bones and tendons
- Voluntary control (consciously controlled)
- Striated (bands of myofibrils visible under a microscope)
- Multinucleated cells (many nuclei in each cell)
- Rapid contraction and relaxation

2. Cardiac Muscle Tissue

- Found in the heart only
- Involuntary control (not consciously controlled)
- Striated
- Branched cells with intercalated discs (connect cells and allow electrical impulses to spread)
- Interconnected myofibrils (contract as a unit)
- Slow and sustained contractions

3. Smooth Muscle Tissue

- Found in the walls of hollow organs (e.g., stomach, intestines)
- Involuntary control
- Non-striated (lacks visible bands of myofibrils)
- Long, spindle-shaped cells
- Contains actin and myosin filaments
- Slow, rhythmic contractions
