Cell Division in Epithelial Tissue The first stage of mitosis is known as prophase, where the nuclear chromatin starts to become organized and condenses into thick strands that eventually become chromosomes observable in the optical microscope. A slice of a trachea. Epithelial Tissue is one of the four types of tissue (epithelial, muscular, connective, and nervous) in animals which consists of closely aggregated polyhedral cells adhering firmly to one another, forming cellular sheets that line the interior of hollow organs and cover the body surface.

Move mouse coursor upon an image. - Epithelial cells are always grounded to a basement membrane, and directly underneath the basement you will find loose connective tissue (areolar) - There are two ways to name epithelial cells, by the shapes of the cells and by how many layers of cells there are (simple vs stratified) (refer to the image) A slice of the esophagus, 10x. Note that whether the epithelial layer of the specimen is on the top, bottom, right, or left of the slice varies with how the specimen slice was positioned on the slide. Simple epithelium is composed of a single layer of cells while stratified epithelium contains several layers. by cariecoleman. Par exemple, la fonction essentielle du tissu musculaire est la contraction. Epithelial tissue is often classified according to numbers of layers of cells present, and by the shape of the cells.

Epithelial tissue is made up of the cell and a small amount of intercellular matrix, while connective tissues are made up of the cell and a huge amount of intercellular matrix. Think about it as a shrink wrap that continues into body cavities. Simple squamous epithelial cells are flattened, i.e., wider than they are tall. Cells are bound together by tight junctions that form an impermeable barrier.

The epithelial layer on one side will face an empty space (or, in some organs, it will face a secreted substance like mucus) and on the other side will usually be attached to connective tissue proper. The arrow indicates an individual columnar epithelial cell.. A. There are three basic shapes used to classify epithelial cells. However, on a microscope slide you may see open spaces around the connective tissues. What are the differences between epithelial and connective tissue? When classifying a stratified epithelial sheet, the sheet is named for the shape of the cells in its most superficial layers. In many cases, these adjustments improved upon their visual appearance. If you just mindlessly started viewing the first edge you find, you have a good chance of looking as something other than the epithelial cells in the preparation.
