This shows an image through the wall of the body of the stomach at low power. You should be able to identify the three major layers seen here - the mucosa, submucosa and muscularis externa. The mucosa is full of gastric glands and pits, and there is a prominent layer of smooth muscle - the muscularis mucosa. The contraction of this muscle helps to expel the contents of the gastric glands. The muscularis externa layer has three layers of muscle.
Types of Muscles. Our bodies have three kinds of muscles. The smooth muscles, the cardiac muscles and the voluntary muscles. Each of these three muscle types have a specific job to do and each of them look entirely different under microscopes.The smooth muscles are the ones that are responsible for parts of the body like the digestive system, the blood vessels, and the kidneys.You have no conscious control of the smooth muscles or the jobs that they do. Our nervous system controls the smooth muscles. We don't control the cardiac muscles either.ach of these three muscle types have a specific job to do and each of them look entirely different under microscopes.
