Here are the essential concepts you must grasp in order to answer the question correctly.
Mucous Membranes
Mucous membranes are specialized epithelial tissues that line various cavities in the body and cover the surface of internal organs. They secrete mucus, which serves to protect and lubricate surfaces, and are involved in absorption and secretion. Understanding the structure and function of mucous membranes is essential for evaluating the statements regarding their cellular composition.

Cell Viability
Cell viability refers to the state of living cells and their ability to maintain metabolic functions. In the context of mucous membranes, it is important to recognize that while the surface cells are alive, they can also be subject to rapid turnover and replacement. This concept is crucial for determining the accuracy of statements about the living status of these cells.

Epithelial Tissue
Epithelial tissue is a type of tissue that forms protective layers on body surfaces and lines cavities and organs. It is characterized by closely packed cells with minimal extracellular matrix. Understanding the properties of epithelial tissue, including its regenerative capacity and the types of cells present, is vital for assessing the truthfulness of statements about mucous membranes.
