A. General Characteristics
Unlike epithelium, connective tissues do not have a free surface. However, on a microscope slide you may see open spaces around the connective tissues.
Connective tissue generally consists of a considerable amount of extracellular material called matrix. Usually there is more extracellular matrix than cellular material. The matrix is composed of varying types of fluids and proteins and fibers.
Connective tissue can be separated into loose and dense connective tissue, cartilage, bone, blood, and adipose.
B. Loose (Areolar) Connective Tissue
This type of connective tissue cushions organs and underlies epithelia. It is characterized by having cells that produce fibers (fibroblasts) and macrophages as well as collagen, reticular, and elastic fibers in the matrix.
