cells of connective tissue proper
Term | Definition |
---|---|
Fibroblasts | Only cells that are always present. Responsible for production of all connective tissue fibers. |
Fibrocytes | Maintain connective tissue fibers of connective tissue proper. Only nucleus is visible in standard histological preparation. Areolar tissue |
Fixed macrophages | Are large cells that engulf damaged cells or pathogens. Areolar tissue |
Adipocytes | Fat cells, containing a single enormous lipid dropet. Adipose tissue, areolar tissue |
Mesenchymal Cells | Stem cells that respond to local injury or infection by dividing to produce daughter cells |
Free Macrophages | Large phagocytic cells...provide a frontline defense |
Mast Cells | Often found near blood vessels. Cytoplasm of a mast cell is filled with secretory granules of histamine. Areolar tissue |
Lymphocytes | Develop into plasmocytes, responsible for production of antibodies |
Collagen Fibers | Most common, strongest fibers. Tendons and ligaments consist of collagen fibers. Areolar tissue. Dense regular connective tissue, dense irregular connective tissue, fibrous cartilage |
Reticular Fibers | Reticular tissue |
Elastic Fibers | Areolar tissue, elastic tissue, elastic cartilage |
Chondrocytes | Only cells found within the cartilage matrix. Hyaline, elastic cartilage, fibrous cartilage |
