[Answer] Cardiac muscle causes movement in the _____.

Answer: organ
Cardiac muscle causes movement in the _____.
Cardiac muscle tissue or myocardium forms the bulk of the heart. The heart wall is a three-layered structure with a thick layer of myocardium sandwiched between the inner endocardium and the outer epicardium (also known as the visceral pericardium). The inner endocardium lines the cardiac chambers covers the cardiac valves and joins with the endothelium that lines the blood vessels that connect to the heart. On the outer aspect of the myocardium is the epicardiumwhich forms part of the pericardium the …
It is not very well known how the electric signal moves in the atria. It seems that it moves in a radial way but Bachmann’s bundle and coronary sinus muscle play a role in conduction between the two atria which have a nearly simultaneous systole. While in the ventricles the signal is carried by specialized tissue called the Purkinje fibers which then transmit the electric charge to the myocardium. If embryonic heart cells are separated into a Petri dish and kept alive each is capable of generating its …
The movements of cardiac muscle are coordinated by a series of electrical impulses produced by specialised pacemaker cells found within the sinoatrial node and the atrioventricular node. Cardiac muscle is composed of myocytes which initiate their internal contractions without…
