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.
The cardiac muscle is the heart, responsible for pumping blood throughout the body. It is made up of cardiac muscle and is the only place in the body where such muscle is found.All the other muscles in the body are composed of either skeletal muscle or smooth muscle.The most muscular part of the heart is its middle layer, called the myocardium, which is mainly responsible for its contractions.t is made up of cardiac muscle and is the only place in the body where such muscle is found.
