## Connective Tissue **Nine different types of connective tissue cells** - Fibroblasts, adipocytes, macrophages, mast cells, plasma cells, eosinophils **What does a matrix refer to?** - Framework of support and biochemical support. **What is the matrix made of?** - Proteins such as glycoproteins, fibrous proteins, and glycosaminoglycans. **What function does the extracellular matrix have?** - Mechanical functions - made of collagen. **What are the two categories of connective tissue cells?** 1. **Fixed Cells** - Fibroblasts - Adipocytes - Macrophages - Mast cells 2. **Transient Cells** - Plasma cells (B cells) - Eosinophils **What is extracellular matrix, also known as?** - Ground substance - Amorphous gelatinous substance - Fills spaces between cells and fibers. - Consists of large protein molecules (Glycosaminoglycans (GAG) - link together making larger molecules: proteoglycans which absorb water. **What are the 3 types of fibers?** - Elastic - Collagen - Reticular
