The connectors of the upper epidermal tissue are known as desmosomes. Desmosomes are specialized structures that form strong intercellular adhesions, helping to hold skin cells together and providing the structural integrity necessary for the epidermis to function effectively as a barrier. They consist of proteins that connect the cytoskeleton of one cell to that of another, which is critical in tissues that experience significant mechanical stress, such as the skin.

While hemidesmosomes are essential for anchoring epithelial cells to the basement membrane, they do not connect adjacent cells; rather, they serve a different function. Adherens junctions help connect the actin cytoskeleton of adjacent cells but are not specific to the upper epidermal layer. Gap junctions, on the other hand, facilitate communication between adjacent cells but do not play a role in providing the tensile strength that desmosomes do. Understanding these differences clarifies why desmosomes are the correct answer in the context of the upper epidermal tissue.
