Connective Tissue Connective is characterized by a sparse cell population scattered through an extensive extracellular matrix . Functions to bind and support other tissues. Matrix is a web of fibers embedded in a homogenous ground substance. Loose connective tissue holds organs in place and attaches epithelia to underlying tissues. Elastic fibers are long threads of the protein elastin.
Elastic properties lend tissue a resilience to quickly return to the original shape.
Reticular fibers are branched and form a tightly woven fabric joining connective tissue to adjacent tissues. Macrophages are phagocytic amoeboid cells that function in immune defense of the body. Insulates the body and stores fuel molecules. Each adipose cell has one large fat droplet which can vary in size as fats are stored or utilized.
