Physiology of cardiac muscle

Nerve supply to cardiac muscle- Histophysiology

Cardiac muscles are under the influence of two major controlling systems.   The autonomic nervous system through the sympathetic and parasympathetic nervous system and under the direct influence of hormonal factors from the adrenal medulla.   Nerve endings are seen close to the cardiac myocytes but there is no specific motor end plate. Their blood supply is from the coronary arteries which are branches of the aorta.   Coronary arteries have assumed important dimensions in clinical practice today because of the high incidence of coronary vaso-occlusive diseases that cause the common heart attack.
