All regionally accredited two-year, four-year, and graduate-level institutions in the United States can apply for designation as a NSA/DHS CAE-CD. CAE designation is valid for five academic years, after which the school must successfully reapply in order to retain its CAE designation.
Through the process of muscle contraction, tension is developed within muscle tissue, which may or may not lead to movement of a part of the body. The term contraction often means to shorten; however, during a muscle contraction the tension may cause muscles to stay the same, get longer or become shorter.The physical process of the contraction happens quickly and in only a few steps.nstead, a muscle contraction of smooth or cardiac muscle is initiated within the organ itself. Within the digestive system, the introduction of food is what causes the contractions to move the food through the system.
Muscle contraction is the activation of tension-generating sites within muscle fibers. In physiology, muscle contraction does not mean muscle shortening because muscle tension can be produced without changes in muscle length such as holding a heavy book or a dumbbell at the same position.f the muscle length changes while muscle tension remains the same, then the muscle contraction is isotonic. In an isotonic contraction, the muscle length can either shorten to produce a concentric contraction or lengthen to produce an eccentric contraction.
