Document Summary
Be familiar with the composition, functions and locations of the two types of supportive connective tissues (cartilage and bone) (see. For composition, know the cells types present, fiber types present and unique composition of the ground substance. Has a firm (semisolid) extracellular matrix that contains collagen and elastic. Chondrocytes (mature cartilage cells) occupy lacunae w/in extracellular fibers matrix. Stronger and more flexible than other ct types with fewer cells. Composition: irregularly arranged chondrocytes in fae; glassy-appearing matrix; very dense; least flexible cartilage. Functions: provides stiff, flexible support; reduces friction between joints. Locations: tip of nose , trachea, larynx, costal cartilage, covering bones at synovial joints (knee, elbow, hip, shoulder) Composition: contains row of collagen fibers ; more flexible than hyaline, less than elastic. Functions: resists compression , acts as shock absorber in. Locations: intervertebral discs, pubic symphysis, pads in knee some joints joints.
