Chapter 13 - Connective Tissue Supports and Protects - BIO 140 - Human When stimulated, macrophages release cytokines, small proteins that act as chemical messengers. They originate in the mesodermal germ layer and differentiate from mesenchyme and hematopoietic tissue in the bone marrow. Lymph drains into blood vessels, delivering molecules to the blood that could not otherwise directly enter the bloodstream. Cytokines recruit other cells of the immune system to infected sites and stimulate their activities. Nonetheless, connective tissues have a common structural plan, and we use areolar connective tissue (ah-re 9 o-lar) as our prototype, or model (Figure 4 and Figure 4 . areolar matrix includes ground substance and the following fibers: adipose matrix includes ground substance and the following fibers: dense connective tissue matrix includes ground substance and the following fibers: connective tissue that transports materials in a plasma matrix is: connective tissue that stores minerals and anchors muscles is, connective tissue that covers and protects the ends of long bones is, compact bone matrix includes nonfibrous ____________. Cartilage and bone are supportive tissue. Wise, Eddie Johnson, Brandon Poe, Dean H. Kruse, Oksana Korol, Jody E. Johnson, Mark Womble, Peter DeSaix. Dense connective tissue proper is richer in fibers and may be regular, with fibers oriented in parallel as in ligaments and tendons, or irregular, with fibers oriented in several directions. Connective tissue is a heterogeneous tissue class with assorted cell shapes and tissue architecture. Collagen, Reticular, Elastic. Cartilaginous tissue is avascular, thus all nutrients need to diffuse through the matrix to reach the chondrocytes. (b) Fibrocartilage provides some compressibility and can absorb pressure. conveys tissue fluid and strengthens organs Areolar tissue is a reservoir for water, salts and fibroblasts What does adipose tissue contain? No blood vessels supply cartilage tissue. Protein fibers fall into three major groups: collagen fibers that are thick, strong, flexible, and resist stretch; reticular fibers that are thin and form a supportive mesh; and elastin fibers that are thin and elastic. Adipose. Fibroblasts are present in all connective tissue proper ([link]).
