The First Taxonomy of Educational Objectives: Cognitive Domain. The idea of creating a taxonomy of educational objectives was conceived by Benjamin Bloom in the 1950s, the assistant director of the University of Chicago's Board of Examinations. Bloom sought to reduce the extensive labor of test development by exchanging test items among universities.
Cardiac muscle tissue is made up of many interlocking cardiac muscle cells, or fibers, that give the tissue its properties. Each cardiac muscle fiber contains a single nucleus and is striated, or striped, because it appears to have light and dark bands when seen through a microscope.ardiac muscle tissue is an extremely specialized form of muscle tissue that has evolved to pump blood throughout the body.
Making the world better, one answer at a time. Cardiac muscle is a type of involuntary striated muscle found in the walls of the heart, particularly the myocardium. Cardiac muscle cells are identified as cardiac myocytes or cardiomyocytes.Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle.Cardiac muscle, different from skeletal muscle, is composed of separate cellular elements. A cardiac muscle cell has a large nucleus and numerous mitochondria.The elevated concentration of mitochondria reveals the huge energy burden that predominant the heart.ardiac muscle, different from skeletal muscle, is composed of separate cellular elements.
