C.T. Introduction: Connective Tissues: General Characteristics and Types • Most abundant tissue in the body • Composition of Intercellular materials determines tissue qualities (From Blood to Bone) General Characteristics of C.T. • Vascular - rich blood supply • Widely scattered cells - large amountt off matrix t i material t i l • Not found on a free surface sandwiched between other tissues I. Proper Connective Tissues: (Has primarily a fluid matrix) 1. Loose Connective Tissue, Areolar • most widely distributed • Location: Combines with Adipose Tissue to form subcutaneous layer (attaches skin to underlying tissues), in all mucus membranes, around blood vessels, around body organs • Function: Wrap & cushion organs, assist in the inflammatory response – holding and moving tissue fluids 2. Loose Connective Tissue, Adipose (Fat) • Location: Accompanies Areolar C.T. & found in subcutaneous layer, and in yellow ll bone b marrow • Function: Serves as an energy reserve, supports & protects organs, reduces heat loss through skin 1 3. Loose Connective Tissue, Reticular • Location: makes up liver, spleen, lymph nodes • Function: Provides framework w/in organ tissue 4. Dense Connective Tissue, Dense Regular • Location: tendons, ligaments, aponeuroses (sheath enclosing muscle) • Function: Provides strong attachment between muscle and bone – withstand stress when pulling force is applied in one direction 5. Dense Connective Tissue, Dense Irregular • Location: periosteum (outer membrane of bone), joint capsules, heart valves, dermis off the th skin ki • Function: Provides strength, withstand stress from many directions A. Hyaline (Gristle) - Most Abundant • Location: covering the ends of long bones (articular cartilage), ventral ends of ribs (costal cartilage), cartilage) nose, nose trachea, bronchi • Function: Support, Flexibility and Reduce Friction in joints II Cartilages II. (Primary cell Chondrocyte) B. Fibrocartilage • Location: symphysis pubis, intervertebral discs • Function: Strength, Rigidity, & Support - Binds one structure to another 2 C. Elastic Cartilage • Location: larynx (voice box), external ear • Function: Flexibility, maintains shape III. Other Connective Tissue • Bone(s) - Osseous Tissue (Primary cell osteocyte) • Blood • Hemopoietic - (Red Bone Marrow) • Lymphatic Structures 3
