Short-acting bronchodilators are called quick-acting, reliever, or rescue medications. These bronchodilators relieve acute asthma symptoms or attacks very quickly by opening the airways.The rescue medications are best for treating sudden asthma symptoms.hort-acting bronchodilators are also used before exercise to prevent exercise-induced asthma. For more information, see WebMD's article on Asthma Inhalers. Short-acting bronchodilators can be used in an asthma nebulizer in the form of a liquid to treat an asthma attack at home.
The other three types are connective tissue, muscle tissue and nervous tissue. Epithelial tissues line the cavities and surfaces of blood vessels and organs throughout the body. There are three principal shapes of epithelial cells: squamous, columnar, and cuboidal.These can be arranged in a single layer of cells as simple epithelium, either squamous, columnar or cuboidal, or in layers of two or more cells deep as stratified (layered), either squamous, columnar or cuboidal.All glands are made up of epithelial cells.hese can be arranged in a single layer of cells as simple epithelium, either squamous, columnar or cuboidal, or in layers of two or more cells deep as stratified (layered), either squamous, columnar or cuboidal.

Epithelial tissue is one of the four basic tissue types. Several features characterize epithelial tissue and distinguish it from connective tissue, muscle tissue, and nervous tissue. 1  Epithelial tissue covers surfaces with an uninterrupted layer of cells. Within the epithelium, the narrow spaces between cells are sealed off from the external environment by cell junctions near the free surface of the cells. 2  Compared to ordinary connective tissue, epithelial tissue has very little interstitial fluid. 3  Epithelial tissue is polarized.
