In which one of the following preparations, cell junctions come across most frequently ?

A. Ligament

B. Tendon

C. Cartilage

D. Ciliated epithelium

Correct Answer :

D. Ciliated epithelium


Cell junctions come across most frequently in the preparation of ciliated epithelium. A cell junction is a structure within a tissue of a multicellular organism. Cell junctions are especially abundant in epithelial tissues. They consist of protein complexes and provide contact between neighbouring cells, between a cell and the extracellular matrix, or they built up the paracellular barrier of epithelia and control the paracellular transport.
