1. General features small number of cells and large amount of extracellular ground substance 2)extracellular is composed of fibers and amorphous ground substance-matrix 3 all of them originate from mesenchyme- embryonal ct 4) have functions of connection, supporting, protecting, nutrition, defence and repairing
