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 wall of the heart is composed of three distinct layers. 2. The outermost layer, the epicardium, is made up of connective tissue and epithelium, and houses blood and lymph capillaries along with coronary arteries. 3. The middle myocardium consists of cardiac muscle and is the thickest layer of the heart wall. 4. The inner endocardium is smooth and is made up of connective tissue and epithelium, and is continuous with the endothelium of major vessels joining the heart. a. The endocardium houses Purkinje fibers.
