smooth muscle
Smooth muscle Tissue have no striations. (there are 3 types of muscle tissue - Skeletal, Cardiac, and Smooth) Smooth propels substances along internal passageways involuntarily.
Smooth muscle (involuntary)lines ducts and vessels.
Smooth muscle plays a crucial role in providing involuntary movement and control of internal organs, blood vessels, and other structures in the body.
Dense bodies are characteristic of smooth muscle cells. These structures help anchor actin filaments in the cell and facilitate muscle contraction by linking adjacent cells. Dense bodies play a crucial role in the mechanical coordination of smooth muscle contraction.
skeletal muscles
These structures do not contain smooth muscle A brain - The brain does not contain muscles!C arm musclesD leg musclesThese DO contain smooth muscle:B heartE intestines
Many tubular structures are made up of smooth muscles. Your small intestine, for example.
The brain, the heart, the lungs, the liver, the gall bladder, the kidneys, the pancreas, the testes, the ovaries, the eyes, and probably more are not made from smooth muscle. The heart. It is made of cardiac muscle fibers.
The two main types of muscle are skeletal muscle and smooth muscle. There is also cardiac muscle but that is only found in the heart so cannot be classed as a 'main type'.The obvious difference between smooth muscle and skeletal muscle is that smooth muscle is not under conscious control whereas skeletal muscle is.Skeletal muscle is used to move the skeleton and smooth muscle is found on the walls of structures and organs.
Well, darling, the type of muscle found in hollow structures like the digestive system is smooth muscle. It's not called smooth because it's suave and charming, but because its fibers don't have the striations that skeletal muscles do. So, next time you're digesting that questionable burrito, just remember it's the smooth muscle doing all the hard work down there.
Smooth muscle can be found in various organs and structures throughout the human body, including the walls of blood vessels, the digestive tract, and the respiratory system.
