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.

Nervous Tissue. Nervous tissue consists of nerve cells and associated supporting cells. All cells exhibit electrical properties, but nerve cells, also called neurons, are specifically designed to transmit electrical impulses from one site in the body to another, and to receive and process information.he nervous system is divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system is limited to the brain and spinal cord, all other nervous tissue belongs to the peripheral nervous system. An individual nerve cell can have components in both the CNS and the PNS.
