The muscle tissue is composed of three types: cardiac, smooth, and skeletal.
1. Cardiac muscle cells are found in the heart’s walls and have a striped (striated) appearance. They are controlled involuntarily.
2. Smooth muscle fibers, with the exception of the heart, are found in the walls of hollow visceral organs (such as the liver, pancreas, and intestines), are spindle-shaped, and are under involuntary control.
3. Muscle fibers that are connected to the skeleton are known as skeletal muscle fibers. They have a striated appearance and are controlled by the user.
