Classification Of Epithelial Tissue

Classification of epithelial tissue location of epithelium the four basic tissue types in the body are the epithelial connective muscular and nervous tissue these tissues exist and function in close association with one another the epithelial tissue or epithelium consists of sheets of cells that cover the external surfaces of the body line the internal cavities form various organs and. Lines open cavities of the digestive and respiratory systems.

Depending on the number of cell layers present the covering epithelia are divided into the following two main types.

Classification of epithelial tissue. Squamous epithelium has cells that are wider than they are tall. Stratified or multilaminar epithelia which consist of two or more layers of epithelial cells. Two forms occur in the human body.

Epithelium ˌ ɛ p ɪ ˈ θ iː l i ə m is one of the four basic types of animal tissue along with connective tissue muscle tissue and nervous tissue epithelial tissues line the outer surfaces of organs and blood vessels throughout the body as well as the inner surfaces of cavities in many internal organs. Glandular epithelium surrounds glands within the body. Classification of epithelial tissues lining and covering epithelia form the boundary between external environment and body tissues cover body surfaces e g the epidermis of the skin and lines the lumens of internal organs that open to the exterior of the body.

Characteristics and classification scheme and types epithelial tissue. The human body is a complex amazing biological machine. Epithelial tissue is a sheet of cells that covers a body surface or lines a body cavity.

There are three principal classifications associated with epithelial cells. 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. Human biology explained is a youtube video series that uses simple drawings to.

An example is the epidermis the outermost layer of the skin. This type of tissue makes up functional units of the thyroid gland salivary glands. Common types of epithelia drawn defined and discussed.

Covers the walls of organs of the closed ventral body cavity. Cuboidal epithelium has cells whose height and width are approximately the same. An epithelium is a sheet of cells that covers a body surface or lines a cavity.

Thyroid salivary epithelial tissue are examples of glandular epithelium whose function is secretion in these glands cuboidal cells are arranged in small spheres and secrete into the cavity formed by the sphere. Covering and lining epithelium forms the outer layer of the skin. Epithelium forms the coverings of surfaces of the body such as skin mouth nasal cavity ectodermal lines internal body surface such as gi tract lungs urinary bladder and vagina endodermal and lining of blood vessels.

Simple or unilaminar epithelia which consist of only a single layer of cells. Columnar epithelium has cells taller than they are wide. Epithelial tissues are thin tissues that cover all the exposed surfaces of the body.
