Question

What are the characteristics of smooth muscle

Answer 1

Hint:
- Cardiac, smooth, and skeletal muscle tissue are the three forms of muscle tissue. Cardiac muscle cells are contained in the heart's walls, are striated, and are regulated involuntarily.
-The muscles of the human body that function with the skeletal system, are under voluntary control, and are concerned with movement, posture, and balance are referred to as the human muscle system.

Complete answer:
Smooth muscle tissue cells have four characteristics: they are involuntarily regulated, not striated, not branched, and have a single nucleus.

Smooth muscle is a form of muscle tissue that is used to apply pressure to vessels and organs through different systems. Sheets or chains of smooth muscle cells make up smooth muscle. These cells have actin and myosin fibers that pass through the cell and are protected by a protein matrix.

Smooth muscle fibres, with the exception of the heart, are contained in the walls of hollow visceral organs, are spindle-shaped, and are regulated involuntarily. Muscle fibers that are bound to the skeleton are known as skeletal muscle fibres. They have a striated appearance and are voluntarily regulated.

Food is moved across the digestive tract by smooth muscles. Smooth muscle folds in the stomach and small intestine aid in the body's absorption of nutrients. Both sphincters in the digestive system are made up of smooth muscle. Smooth muscle in the bladder helps to drive urine out.

Smooth muscle is divided into two types: single-unit smooth muscle, which is the most common, and multiunit smooth muscle, which is less common. Both styles are found in various parts of the body and have distinct characteristics.

Smooth muscle is located in the walls of hollow organs such as the urinary bladder, uterus, stomach, and intestines, as well as in the walls of passageways such as the arteries and veins of the circulatory system, and the tracts of the respiratory and urinary systems.

Note: Muscle is a form of soft tissue that can be found in most animals. Actin and myosin protein filaments slide past one another in muscle cells, causing a contraction that shifts the length and shape of the cell.
