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.
Cardiac muscle tissue is made up of many interlocking cardiac muscle cells, or fibers, that give the tissue its properties. Each cardiac muscle fiber contains a single nucleus and is striated, or striped, because it appears to have light and dark bands when seen through a microscope.ardiac muscle tissue is able to set its own contraction rhythm due to the presence of pacemaker cells that stimulate the other cardiac muscle cells. The pacemaker cells normally receive inputs from the nervous system to increase or decrease the heart rate depending on the bodyâs needs.
