Properties of Cardiac Muscle
- Automaticity: The main property of the cardiac muscle is to produce impulses which gives the rhythmicity in the heart.
- Contractility: The cardiac muscle posses contraction and relaxation which helps in the regular pumping of blood across the heart.
- Excitability: It is the ability of a cell to respond to certain stimulus.
- Conductivity: The cardiac muscle fiber serves the function of transmission of electrical currents from one cell to another cell.
Diagram of Cardiac Muscles
The diagram of cardiac muscle shows the thick middle layer (myocardium) between the outer layer of the heart wall (the pericardium) and the inner layer (the endocardium). The diagram of cardiac muscle class 9 is often asked in the examinations. This muscle is crucial for pumping blood throughout the body and ensures oxygen and nutrients reach all the tissues and organs.
