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.
Answer:
Different types of intercellular junctions, including plasmodesmata, tight junctions, gap junctions, and desmosomes. Plasmodesmata (singular form: plasmodesma) are intercellular organelles found only in plant and algal cells. Tight junctions are located within our body's epithelia. Epithelia is the plural of epithelium. Epithelium is a word that refers to the covering of the body's internal and external surfaces. This includes organs (such as skin), blood vessels, and cavities. Gap junctions are found in many places throughout the body. This includes epithelia, which are the coverings of body surfaces, as well as nerves, cardiac (heart) muscle, and smooth muscle (such as that of the intestines). Desmosomes are prominently found in cardiac muscle
