CONNECTIVE TISSUE

Connective Tissue encompasses a large group of Tissues that develop from the mesenchyme. Morphologically, it is characterized by a well-developed Extracellular matrix consisting of fibrous structures and ground substance. Some types of connective tissue are also distinguished by a variety of Cell types. The physicochemical properties and Structure OF THE extracellular matrix largely determine the Functional Significance of the various types of connective tissue.

Connective tissue performs several vital Functions: mechanical, supportive, and shape-forming—forming the capsule and stroma of numerous Organs, ligaments, tendons, Cartilage, and bones; protective, carried out through mechanical defense, phagocytosis, and The production of immune bodies; plastic, manifested through active participation in regeneration and wound healing processes; trophic, associated with the Regulation of Cell Nutrition and their involvement in METABOLISM; homeostatic—maintaining the constancy of the body's internal environment; and regulatory—influencing The activity of other tissues via BIOLOGICALLY ACTIVE SUBSTANCES.

Connective tissue is subdivided into Fibrous connective tissue, skeletal connective tissue (cartilage and Bone tissue), and Connective tissue with special properties. The latter include reticular, adipose, pigmented, and mucous tissues.
