Verified step by step guidance

Understand the structural characteristics of epithelial tissue. Epithelial tissue is known for its cellularity, meaning it is composed almost entirely of cells with minimal extracellular matrix.

Recognize that epithelial tissue is avascular, meaning it does not contain blood vessels. Nutrients are obtained through diffusion from underlying tissues.

Identify the polarity of epithelial tissue, which refers to the presence of distinct apical and basal surfaces. The apical surface faces the body cavity or exterior, while the basal surface is attached to the underlying connective tissue.

Consider the characteristic of abundant extracellular matrix. Epithelial tissue typically has very little extracellular matrix compared to other tissue types like connective tissue.

Determine which characteristic is not typical of epithelial tissue. Given the options, 'Abundant extracellular matrix' is not a structural characteristic of epithelial tissue, as epithelial tissue is primarily cellular with minimal extracellular matrix.
