What are the main types of connective tissues?

Connective tissues are basically divided into three categories viz., con­nective tissue proper, Skeletal tissue and Fluid tissue (Vascular tissue). The cells of the connective tissue proper are immersed in a soft jelly like matrix chemically composed of carbohydrates linked to proteins. The connective tissues proper connect one tissue to another and form protec­tive sheaths around organs.

Connective tissue proper is divided into five categories namely Areolar tissue, Adipose tissue, white fiberous tissue, Yellow elastic tissue and re­ticular tissue. In some cases only three are recognized namely Areolar tissue, fibrous tissue and adipose tissue.
