A myocyte is composed of multiple myofibrils, which contain the “contractile units” of the muscle known as a sarcomere. WebAbstract. All the myocytes within the heart have the capacity to conduct the cardiac impulse. A population of myocytes is specialized so as to generate the cardiac impulse and then to conduct it from the atrial to the ventricular chambers. This population has become known as the conduction system. Anatomists who seek to demonstrate the location ...
