Nonstriated muscle, also known as smooth muscle, is one of the three types of muscle tissue found in the human body. It is called nonstriated because its cells lack the striations or crosswise bands that are characteristic of skeletal and cardiac muscle tissue.
Structure of Nonstriated Muscle
Nonstriated muscle is made up of spindle-shaped cells that are shorter than skeletal muscle cells. These cells contain a single nucleus and have a tapered end. Nonstriated muscle cells are involuntary, meaning they contract without conscious control.
Function of Nonstriated Muscle
Nonstriated muscle is found in the walls of hollow organs such as the stomach, intestines, blood vessels, and bladder. Its function is to help these organs contract and relax to facilitate processes like digestion, circulation, and urination.
Regulation of Nonstriated Muscle
Unlike skeletal muscle, nonstriated muscle is regulated by the autonomic nervous system and hormones. This regulation allows for the coordinated contraction and relaxation of nonstriated muscle in response to various stimuli.
Comparison with Striated Muscle
Nonstriated muscle differs from striated muscle, such as skeletal and cardiac muscle, in terms of structure, function, and control. While striated muscles are under voluntary control, nonstriated muscles are involuntary and contract slowly and rhythmically.
In conclusion, nonstriated muscle plays a crucial role in the functioning of various organs in the body. Its unique structure and involuntary nature make it essential for processes like digestion, circulation, and excretion.
Nonstriated Examples
- The nonstriated muscle in the digestive system helps move food through the intestines.
- Cardiac muscle is striated, while smooth muscle is nonstriated.
- Nonstriated muscle cells do not have the same banding pattern as skeletal muscle cells.
- The nonstriated muscle in blood vessels helps regulate blood pressure.
- Smooth muscle is an example of a nonstriated muscle type found in internal organs.
- The nonstriated muscle fibers in the bladder help with urine control.
- Involuntary muscle contractions in nonstriated muscles are controlled by the autonomic nervous system.
- Nonstriated muscle tissue is found in the walls of hollow organs like the stomach and intestines.
- Smooth muscle is another term used to describe nonstriated muscle tissue.
- Nonstriated muscle cells contain a single nucleus compared to multinucleated skeletal muscle cells.
