A gingival epithelial cell is attached to the basal lamina. which type of cell junction allows the cell to attach to the basal lamina?

Answer :

To the basal lamina is a gingival epithelial cell connected Hemidesmosome

Cell junction type enables the cell to adhere to the basal lamina.

Hemidesmosomes are incredibly tiny, stud-like structures that are located in the keratinocytes of the skin's epidermis and that connect to the extracellular matrix. By using electron microscope to see them, they resemble desmosomes in shape, yet desmosomes cling to other cells.

Given that they both bind cells to the extracellular matrix, hemidesmosomes and focal adhesions can also be compared. Hemidesmosomes use integrins in place of desmogleins and desmocollins in the extracellular space. Hemidesmosomes are present in the epithelial cells that join the basal epithelial cells to the basal lamina's lamina lucida. In signaling pathways like keratinocyte migration or carcinoma cell infiltration, hemidesmosomes are also implicated.
