What is a simple spinocellular epithelium?
Simple spinocellular epithelium is a type of epithelial tissue characterized by a single layer of spinocellular epithelial cells. With the epithelial line, most of the body organs and form one of the main types of body, along with nervous, connective and muscle tissue. The epithelium is divided by the form and functions into three main types: block, spinocellular and columnar. The scenario cells are flat and primarily operate in the processes of secretion, diffusion and filtration. Epithelial cells arranged in one layer are called simple epithelium and epithelial tissue with more than one layer is considered stratified.
Under the microscope, a simple spinocellular epithelium appears flat and irregular, similar to a scale or fried eggs placed side by side. One can also see round, dark stained stains in the middle of each cell, which is a core. Because there is only one layer of cells, each cell is in contact with the basal membrane or basal laminate, a fibrous leaf that anchor the epithelium of the KZil organ. SideThe basal membrane is called the basal surface and the exposed surface is called the apical surface. Like other types of epithelium, a simple spinocellular epithelium is arranged with a very small intercellular space or gaps between the cells and cells are connected laterally or on the sides.
Simple spinocellular epithelium has a unique characteristic of a very large surface area due to its width. This makes it suitable for fast diffusion and filtration. Diffusion is the process of particles moving from the site of a higher concentration to the site of a lower concentration. For example, when a well -nourished blood passes through a hungry cell, nutrients spread through the wall of the blood vessel into the cell because the blood has a higher concentration of nutrients than the cell. Filtration is a process in which fluids move due to hydrostatic pressure.
Simple The epithelial scenario is found in alveoli in the lungs, blood vessels endothelium, glomerulus and tubules in lEdvinách, mesothel. In alveoli or in structures similar to grapes in the lungs, a simple spinocellular epithelium diffuse gases in and out of the bloodstream within breathing. Simple spinocellular epithelium in the endothelium or thin interior lining of all blood vessels helps blood flow and regulates the passage of white blood cells and other substances from the bloodstream. In the glomerulus and tubules in the kidney, this epithelium performs filtration and diffusion to regulate the body of the body and secrete waste. Mesothelium or a thin membrane that surrounds the heart, lungs and many organs in the abdomen, protects the organs by creating a cunning film that prevents organs from friction or hold together.
