Connective Tissue Flashcards
Connective Tissue
Supports, connects, and protects body structures
Matrix
Consists of fluid and fibers
Fibroblasts
Release fibers into matrix
Macrophages
Engulf and digest foreign substances
Mast Cells
Release heparin and histamine
Heparin
Prevent blood clotting
Histamine
Triggers inflammatory response
Specialized Connective Tissue
Includes cartilage, blood cells, bone, and adipose tissue
Adipose Tissue
Stores fat and located at subcutaneous layer
Cartilage
Flexible connective tissue that protects joints and bones
Chondrocytes
Cartilage cells
Osteocytes
Mature bone cells
Osteons
Functional units of compact bone
Trabeculae
Functional units of spongy bone
Tight Junctions
Prevent flow of substances between cells
Gap Junctions (Like Tunnels)
Allow substances to pass between cells
Desmosomes
Connect intermediate filaments of neighboring cells (allowing some flow)
Hemidesmosomes
Attach epithelial tissue to the basement membrane
