Building Blocks of Connective Tissue

Match the following vocabulary to the correct description.

• collagen fiber

• this fiber forms a net-like scaffolding arrangement

• elastic fiber

• the "filling" between the fibers and the cells

• ground substance

• this fiber is able to stretch and recoil

• extracellular matrix

• all materials found outside of the cells

• reticular fiber

• the strongest/largest/most abundant fiber

Match the following cells to their role in connective tissue.

• fat cells; energy storage

• mast cells

• make protein antibodies

• plasma cells

• produce the extracellular matrix of CT

• fibroblasts

• engulf foreign substances/invaders

• macrophages

• release histamine for local inflammation

• adipocytes
