Definition - What does Cellular Network mean? A cellular network is a radio network distributed over land through cells where each cell includes a fixed location transceiver known as base station. These cells together provide radio coverage over larger geographical areas.
A cell junction (or intercellular bridge) is a type of structure that exists within the tissue of some multicellular organisms, such as animals.Cell junctions consist of multiprotein complexes that provide contact between neighbouring cells or between a cell and the extracellular matrix.nvertebrates have several other types of specific junctions, for example septate junctions or the C. elegans apical junction. In multicellular plants, the structural functions of cell junctions are instead provided for by cell walls. The analogues of communicative cell junctions in plants are called plasmodesmata.
