Bone, Cartilage, and Blood, and Connective Tissue Proper
Derived from Mesenchyme

Fibroblasts...the most common cells in the body:  *Note the histiocyte, a phagocytic monocyte

Two kinds of connective tissue below:

Blood Continued:

     Mast Cell (metachromatic staining, very granulated, produces SRS-A, ECF-A, histamine):

     Macrophage (Not as well define as monocyte progenitor) :

     Plasma Cell (negative staining Golgi, making antibody):

                                      

Collagen:

Reticular Fibers:

Elastic Fibers (agyrophilic...they love silver):
