Decades of research have investigated the possible treatment of the symptoms of schizophrenia with several of the B vitamins. Thiamine (Vitamin B1): When taken with acetazolamide (more usually prescribed for glaucoma or epilepsy), this vitamin may improve a variety of symptoms of schizophrenia. Niacin (Vitamin B3):
Coordinated contractions of cardiac muscle cells in the heart propel blood out of the atria and ventricles to the blood vessels of the left/body/systemic and right/lungs/pulmonary circulatory systems.This complex mechanism illustrates systole of the heart.he cells that constitute cardiac muscle, called cardiomyocytes or myocardiocytes, contain only three nuclei. The myocardium is the muscle tissue of the heart, and forms a thick middle layer between the outer epicardium layer and the inner endocardium layer.
Layers of the Heart. The heart consists of three layers in all. This Buzzle article explains the structure and function of each of these layers. The heart is one of the most important organs present in the human body. This organ is responsible for pumping blood to all parts of the body. Thus, it is considered as the main organ of the circulatory system. The heart is made up of specialized, smooth muscle tissue known as cardiac muscles or myocardium.
