What type of tissue is referred to as epithelial?

Epithelial tissue is a type of tissue that forms the protective layers covering the surfaces of the body, both inside and out. This includes the skin and the lining of internal organs and body cavities. Epithelial tissue serves several essential functions, such as protection, absorption, secretion, and sensation.

The reference to membranous tissue covering internal organs aligns with the characteristics of epithelial tissue, as it forms boundaries that separate different environments in the body while also playing a critical role in various bodily functions. Epithelial cells are closely packed together with minimal extracellular matrix, which is distinct from other tissue types where there may be more space between cells.

The other options describe different types of tissue that do not embody the characteristics of epithelial tissue. Muscular tissue, connective tissue, and nervous tissue serve different functions within the body and have unique structures and roles that are not related to the functions of epithelial tissue. This emphasizes the importance of identifying the specific roles and properties that distinguish epithelial tissue from other tissue types in the body.
