Final answer:
Three features of the basal epithelial surface are desmosomes, hemidesomes, and the basement membrane, all of which are crucial for maintaining the structure and stability of epithelial tissues.
Step-by-step explanation:
Three features of the basal epithelial surface are desmosomes, hemidesmosomes, and the basement membrane. These structures play a critical role in maintaining the integrity of epithelial tissues. Desmosomes and hemidesomes are anchoring junctions that provide strong and flexible connections, helping to stabilize the cells within the tissue. The desmosomes facilitate the linking of cells to one another, while hemidesmosomes connect cells to the extracellular matrix, particularly to the basal lamina. The basement membrane, formed by the basal lamina and reticular lamina, supports the epithelial layer and attaches it to the underlying connective tissues. Understanding the functions of these features is essential for comprehending the overall structure and function of epithelial tissue.
