| fibrous pericardium - | made of tough white fibrous connective tissue that forms a loose, inextensible outer covering of the heart |
| serous pericardium | moist , serous membrane covering the entire outer surface of the heart known as the visceral layer or epicardium |
| SA node | known as the pacemaker, normal cardiac impulse initiates mechanial contraction |
| P wave | represents depolarization of the atria , caused by the passage of an electrical impulse from the SA node through the musculature of both atria . |
| QRS complex | depolarization of the ventricles, depolarization of the interventricular septum and spread of depolarization by the subendocardial branches (Purkinje fibers) through the lateral ventricular walls. |
| T-wave | repolarization of the ventricles |
| Immunoglobulin M (IgM) | antibody that immature B cells synthesize and insert into their plasma membranes. |
| Immunoglobulin A (IgA) | antibody present in the mucous membranes of the body , in saliva , and in tears |
