Question

What is visceral muscle? Where is it found?

Answer 1

Hint: There are three types of muscle tissue: cardiac, smooth, and skeletal. Cardiac muscle cells are located in the wall of the heart, they are striated and are under involuntary control. Smooth muscle fibers are found in the walls of hollow visceral organs other than the heart, are spindle-shaped, and are also involuntarily controlled. Skeletal muscle fibers appear in muscles attached to bones. They have a striated appearance and are under voluntary control.

Complete answer:
Visceral or smooth muscles are located in organs such as the stomach and intestines, as well as blood vessels. It is called smooth muscle because, unlike skeletal muscle, it does not have the band-like appearance of skeletal muscle or heart muscle. Visceral muscles are the weakest of all muscle tissues and contract to move matter through the organs.
Because the visceral muscles are controlled by the unconscious part of the brain, they are called involuntary muscles because they cannot be controlled by the conscious mind.
Known as general smooth muscle or visceral muscle, this type of smooth muscle is the most common in the human body and forms the walls of hollow organs. A single unit of smooth muscle produces a slow and steady contraction, allowing food and other substances from the digestive tract to pass through the body. Since most smooth muscles must work uninterrupted for a long time, their energy production is relatively low to minimize energy requirements.

Note:
Although smooth muscle cells do not have stripes, smooth muscle fibers have actin and contractile myosin proteins, which interact to generate tension. These fibers are not arranged in ordered sarcomeres (therefore, without stripes), but are anchored in dense bodies dispersed throughout the cytoplasm and anchored to the muscle membrane. The network of intermediate fibers runs between dense bodies and provides an internal framework for protein reduction.
