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.
The heart is made of a special kind of muscle called myocardium, and is enclosed in a double-layered, membranous sac called a pericardium. The heart lies in the chest cavity between the lungs. It is composed of four chambers, many large arteries and many veins. The four chambers are called atrium and ventricles. A wall of muscle divides the heart into two cavities: the left cavity pumps blood throughout the body, while the right cavity pumps blood only through the lungs. Two chambers of the heart lie in the left cavity and two chambers lie in the right cavity.
