It is under the control of the autonomic nervous system‚ however‚ even without nervous imput contractions can occur due to cells called pacemaker cells. Cardiac muscle is highly resistant to fatigue due to the presence of a large number of mitochondria‚ myoglobin and a good blood supply allowing continuous aerobic metabolism.

When it comes to muscle contraction‚ contraction takes place in the muscle fibers. Muscle fibers are the basic building blocks of the muscle and what allow muscles to contract. They appear as long cylinder cells that contain several nuclei. Contraction happens when the muscle receive signals from the nervous system and the Neuromuscular Junction obtains the muscular exchange where the synaptic bulb and the muscle fibers connect. muscle fibers are composed of myofibrils‚ which contain contractile
