In which one of the following preparations are you likely to come across cell junctions most frequently?

Cell junctions are specialised structures that link neighbouring cells structurally and functionally.
They are found in epithelial tissue, where the cells are compactly packed with very little intercellular matrix.
Three types occur: tight junctions (stop substances from leaking across the tissue), adhering junctions (cement neighbouring cells together) and gap junctions (allow cells to communicate by connecting their cytoplasm).
Ciliated epithelium is an epithelial tissue whose closely packed cells bear cilia on their free surface, so cell junctions are seen most frequently in it.
Tendon and hyaline cartilage are connective tissues in which the cells lie far apart in an abundant matrix.
Thrombocytes (platelets) are free cell fragments floating in the blood.
So cell junctions are most frequent in ciliated epithelium.
