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
