Skeletal and smooth Muscle
|
Detailed explanation-1: -Smooth muscle fibers are located in walls of hollow visceral organs (such as the liver, pancreas, and intestines), except the heart, appear spindle-shaped, and are also under involuntary control.
Detailed explanation-2: -Smooth muscle differs from skeletal muscle in a variety of ways, perhaps the most important being its ability to be contracted and controlled involuntarily. The nervous system can use smooth muscle to tightly regulate many of the body’s subsystems for life with no thought from the user.
Detailed explanation-3: -Smooth muscle fibres are unbranched and spindle in shape. They are unstriated and consist of a single nucleus. These muscles are present in the lining of several internal organs as they perform involuntary actions.
