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.

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.
