Study Notes
Types of Connective Tissue Cells
- Nine types include fibroblasts, adipocytes, macrophages, mast cells, plasma cells, and eosinophils.
- Fixed cells include fibroblasts, adipocytes, macrophages, and mast cells.
- Transient cells consist of plasma cells (B cells) and eosinophils.
Matrix in Connective Tissue
- The matrix provides structural and biochemical support within connective tissue.
- Composed of glycoproteins, fibrous proteins, and glycosaminoglycans (GAGs).
- GAGs form proteoglycans which serve to absorb water and create a gel-like substance.
Extracellular Matrix (ECM)
- Also known as ground substance, it is an amorphous gelatinous material.
- Fills spaces between cells and fibers, contributing to tissue integrity.
Functions of the Extracellular Matrix
- Provides mechanical support, primarily through the collagen fibers present in the matrix.
Types of Fibers in Connective Tissue
- Three main fiber types include elastic, collagen, and reticular fibers.
Role of Fibrous Connective Tissue
- Fibrous connective tissue supports and protects organs, anchoring bones and muscles.
Calcification of the Matrix
- When the connective tissue matrix is calcified, it can develop into bone and teeth.
Major Component of the Matrix
- Water is the principal component, aiding in the hydration and function of the connective tissues.
