Epithelial Tissue Characteristics And Classification Scheme And Types

Epithelial Tissue Characteristics And Classification Scheme And Types Classification scheme of epithelial tissue: typically epithelial tissue is classified on the basis of arrangement and shape of cells. for naming the tissue types, the arrangement of the cells is stated first, then the shape, and is followed by “epithelium” to complete the naming. for example; simple squamous epithelium. 1. Classification by cell shapes of epithelial cells. there are three principal shapes of epithelial cells: squamous, cuboidal, and columnar. squamous epithelium: squamous epithelial cells are flat and scale like in appearance. they can be found in the smooth lining of the mouth, esophagus, and the alveoli of the lungs.

Epithelial Tissue Characteristics And Classification Scheme And Types Epithelial tissue is one of the four tissue types. it is found lining the inner and outer body surfaces and comprising the parenchyma of the glands. it is divided into surface (covering) and glandular (secreting) epithelium. surface epithelium consists of one or more cell layers, stacked over a thin basement membrane. Classification of epithelial tissues epithelial tissues are classified according to the shape of the cells composing the tissue and by the number of cell layers present in the tissue.( figure 4.2.2 ) cell shapes are classified as being either squamous (flattened and thin), cuboidal (boxy, as wide as it is tall), or columnar (rectangular, taller. Epithelial tissue is composed of cells laid together in sheets with the cells tightly connected to one another. epithelial layers are avascular, but innervated. epithelial cells have two surfaces that differ in both structure and function. glands, such as exocrine and endocrine, are composed of epithelial tissue and classified based on how. Epithelial tissue definition. epithelial tissues are thin tissues that cover all the exposed surfaces of the body. they form the external skin, the inner lining of the mouth, digestive tract, secretory glands, the lining of hollow parts of every organ such as the heart, lungs, eyes, ears, the urogenital tract, as well as the ventricular system of the brain and central canals of the spinal cord.

Classification of epithelial tissues. epithelial tissues are classified according to the shape of the cells and number of the cell layers formed (figure 3.3.3 3.3. 3). cell shapes can be squamous (flattened and thin), cuboidal (boxy, as wide as it is tall), or columnar (rectangular, taller than it is wide). Epithelial tissue, also referred to as epithelium (plural: epithelia), refers to the sheets of cells that cover exterior surfaces of the body, line internal cavities and passageways, and form certain glands. skin is not the only area of the body exposed to the outside. other areas include the airways, the digestive tract, as well as the urinary.
