Which of the Following is a Function of the Cardiac

Question

Which of the following is a function of the cardiac skeleton of the heart?
A) isolates atrial and ventricular muscle cells
B) provides instructions for cardiac muscle cells to contract
C) maintains the energy reserves in the form of glycogen and lipid inclusions
D) provides full range mobility to the valves of the heart
E) physically connects the atrial muscle cells to the ventricular muscle cells

Accepted Answer

The cardiac skeleton separates and isolates atrial and ventricular muscle cells, allowing them to contract independently and efficiently. It also provides support for the valves and electrical conduction system of the heart. It does not provide instructions for cardiac muscle cells to contract, maintain energy reserves, or physically connect the atrial and ventricular muscle cells.
