Question

multiple choice question
why does the myocardium thicken with age?
o it thickens because of fat and fibrous connective tissue accumulation.
o it thickens because the cardiac muscle cells continue to divide, increasing in number.
o it thickens because of increased vascular permeability.
o it thickens because the endothelium thickens.

Explanation:

Cardiac muscle cells do not divide significantly in adults. Increased vascular permeability and endothelium thickening do not directly cause myocardial thickening. Fat and fibrous connective - tissue accumulation with age can lead to myocardial thickening.

Answer:

It thickens because of fat and fibrous connective tissue accumulation.
