General characteristics of C.T. Have small number of cells but have much extracellular matrix. The cells in connective tissue have no polarity, and they are widely separated in the extracellular matrix. Have no basement membrane, but have blood vessel and nerve. Function as: connecting, supporting, protecting, nutrition, defense and repairing
