To review:
Match the term cardiocytes to the closely related descriptions given below:
1. Vein to the left atrium
2. Covers the outer surface of the heart.
3. Supplies blood to the heart muscle
4. Lines inner surface of the pericardial sac
5. Slow heart rate
6. Cardiac muscle cells
7. The muscular wall of the heart
8. Relaxation phase of the cardiac cycle
9. Vein to the right atrium
10. Contraction phase of the cardiac cycle.
Introduction:
The cells of the heart are known to be more complex as compared to the muscle cells. The functional cells of the heart are labeled as myocytes and these are suggestive of their functions as muscle tissue. The cardiac cycle is basically the performance of the heart from the starting of one heartbeat to the beginning of the next one.
Explanation of Solution
The contractile cells of the heart were known as myocytes which indicates their fundamental character. Every functional cardiac cell present basically incorporates both the neurological and muscular capability. Therefore, the cells are known to be neuromylocytes. The cardiocyte comprises three functional activities, the contractile region comprising of the sarcomere and the sarcoplasmic reticulum which present in the center. Along with this, the neural region is present on the left side which is linked with the electrical stimulation.
Therefore, it can be concluded that the cardiocytes can be correctly matched with cardiac muscle cells.
