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.
There are three types of muscle cells: skeletal, cardiac, and smooth muscle tissue (Figure 5). Contractions of the skeletal muscles, which are attached to bones, cause the bones to move. Cardiac muscle contracts to force blood out of the heart and around the body.ervous tissue is made up of different cells working together to  perform a given function -- in this case, to carry messages from  one part of the body to another. Differen â¦ t nervous tissues working  together make up nervous system organs, such as nerves, the spinal  cord, or the brain.
