Question

a 65 - year - old patient has thickened left ventricular muscle. what type of cellular change describes this?
hypertrophy
hyperplasia
metaplasia
atrophy

Explanation:

Hypertrophy is an increase in the size of cells, leading to an increase in the size of the organ. In this case, the left ventricular muscle thickens due to an increase in the size of cardiac muscle cells (hypertrophy). Hyperplasia is an increase in the number of cells. Metaplasia is the replacement of one type of differentiated cell with another. Atrophy is a decrease in the size of cells and organs. So the answer is Hypertrophy.

Answer:

Hypertrophy
