Surrounding each muscle fiber (cell) is a delicate external lamina composed primarily of reticular fibers. This external lamina is produced by the muscle fiber and, when observed through the light microscope, cannot be distinguished from the cell membrane of the muscle fiber, the sarcolemma.
1 Surrounding the mucosa is the submucosa layer of the stomach. 2  The submucosa is made up of various connective tissues, blood vessels, and nerves. 3  Connective tissues support the tissues of the mucosa and connect it to the muscularis layer. The esophagus connects to the stomach at a small region called the cardia. 2  The cardia is a narrow, tube-like region that opens up into the wider regions of the stomach. 3  Within the cardia is the lower esophageal sphincter, a band of muscle tissue that contracts to hold food and acid inside of the stomach.
