Identify the cells found in connective tissue proper
What will be an ideal response?
Answer:
Fibroblasts: only cell that is always present in connective tissue proper
Fibrocytes: spindle-shaped cell that maintains the connective tissue fibers of connective tissue proper
Adipocytes: fat cells
Mesenchymal cells: stem cells that respond to local injury or infection by dividing to produce daughter cells that differentiate into fibroblasts, macrophages, or other connective tissue cells.
Melanocytes: synthesize and store melanin
Macrophages: Engulf damaged cells or pathogens to protect the cell
Mast cells: circulate in the blood and are filled with histamine (released after injury or infection, stimulates local inflammation) and heparin (anticoagulant that enhances local blood flow during inflammation and reduces the devlopement of blood clots in areas of slow moving blood)
Lymphocytes: Congregate wherever tissue damage occurs, may develop into plasma cells, which produce antibodies
Microphages: phagocytic blood cells (respond to invading bacteria, regulate the inflammatory response, defend against parasites and play a role in allergic reactions) aka white blood cells
