Answer: D. Contractility of the heart muscle refers to the force of contraction that this muscle can exert.
Explanation:
The myocardial contractility is ability of the heart muscles to contract. This is achieved by the forces which develop between the contracting muscles caused by the filaments of actin and myosin.
The degree of binding of the muscle filaments dependents upon the calcium ion concentration. These actions are controlled in vivo by the sympathetic nervous system. It is driven by the release of the catecholamine, which is a process which determines the calcium ion concentration inside the cytosol of the muscles of the heart.
