Study Notes
Connective Tissue Components
- Fibroblasts are the most common cells in connective tissue proper.
- Fibroblasts originate from mesenchymal cells in connective tissue proper.
- The main function of fibroblasts is to synthesize collagen and other extracellular matrix components.
Protein Synthesis
- Fibroblasts synthesize collagen, the most abundant protein in the human body.
- Fibroblasts also synthesize proteoglycans, which comprise the ground substance in tissues.
Stem Cells
- Mesenchymal stem cells are undifferentiated cells, also known as multipotential or pluripotential stem cells.
Leukocytes
- Neutrophils are commonly associated with bacterial infections.
Fiber Types
- Reticular fibers are mainly found in the body, specifically in the spleen, liver, and lymph nodes.
- Collagen is a major component of the extracellular matrix of connective tissue.
- Elastin is the protein that imparts a yellowish color to elastic fibers.
- Elastic fibers allow for stretch and recoil of tissues in the body.
Edema
- Edema, or the excessive accumulation of interstitial fluid, is commonly observed in tissues.
- Edema is caused by forces such as hydrostatic pressure, osmotic pressure, and increased permeability of blood vessels.
Extracellular Matrix
- Fibroblasts are responsible for producing the extracellular matrix in connective tissue.
- Proteoglycans help stabilize the ECM by binding to other matrix components and cell membranes.
- Reticular fibers play a crucial role in maintaining the structure of organs.
Cell Types
- Mesenchymal cells are derived from the mesoderm and play a crucial role in maintaining the structure of organs.
