Functions of Connective Tissue Quiz

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.
