Bloomâs Taxonomy. Bloomâs taxonomy is a classification system used to define and distinguish different levels of human cognitionâi.e., thinking, learning, and understanding.
Cardiac Muscle Tissue. Cardiac muscle tissue is an extremely specialized form of muscle tissue that has evolved to pump blood throughout the body. In fact, cardiac muscle is only found in the heart and makes up the bulk of the heartâs mass. The heart beats powerfully and continuously throughout an entire lifetime without any rest, so cardiac muscle has evolved to have incredibly high contractile strength and endurance.
An isolated cardiac muscle cell, beating Cardiac muscle (heart muscle) is striated muscle (striped muscle) in the walls of the heart. It makes up the tissue called the myocardium. It is involuntary: a person cannot control it consciously. Cardiac muscle is one of three main types of muscle, the others being skeletal and smooth muscle. The cells that make up cardiac muscle have one (74%) or two (24.5%) nuclei. The myocardium forms a thick middle layer between the outer epicardium layer and the inner endocardium layer.
