| Question | Answer |
| Generally speaking, what kind of CT is this? | Loose |
| Generally speaking, what kind of CT is this? | Dense, regular |
| Generally speaking, what kind of CT is this? | Dense, irregular |
| What type of cell is the black arrow point at? | Plasma cell |
| What type of connective tissue is this? | Bone |
| What type of connective tissue is this? | Adipose (both white and brown) |
| What type of connective tissue is indicated by the white arrow? | Mesenchymal connective tissue |
| What type of cell is indicated by the white arrow? | Eosinophil |
| Generally speaking, what type of connective tissue is this? | Cartilage |
| What type of cell is indicated by the white arrow? | Macrophage |
| Most important and abundant long-lived CT cells; make CT fibers and ground substance; proliferate in wound healing process, making scar tissue | Fibroblasts (fibrocytes when they are inactive) |
| 2 forms of adipocytes | Unilocular (white) Multilocular (brown) |
| Also called histiocytes; have an abundant “foamy” cytoplasm; essentially perform the “janitor” work | Macrophages |
| Contain many secretory granules that are basophilic; important in the allergic and inflammation response; metachromatic | Mast cells |
| “Activated” B lymphocytes that secrete large amounts of antibodies; very numerous in mucosa CT of the gut | Plasma cells |
| Stem cells in CT that have to potential to differentiate into nearly all CT cell’s; very rare in adult tissues; “star-shaped” | Mesenchymal cells |
| 3 types of CT fibers | Collagen, reticular, elastic |
| “White fibers” Function: high tensile strength; Acidophilic | Collagen fibers |
| Types of collagen fibers | Types I-IV |
| The most predominant type of collagen in CT proper | Collagen type I |
| These type of collagen fibers are found in cartilage | Type II |
| Form a delicate network for highly cellular tissues (lymphoid tissues, spleen, bone marrow, etc.) | Reticular fibers |
| Reticular fibers need to be stained with silver stains in order to be visualized, thus they are called ___ | ARGYROPHILIC |
| “Yellow fibers” | Elastic fibers |
| Elastic fibers require which kind of stain? | Verhoeff staining |
| How to classify CTs (i.e., what are the 3 criteria used to classify CT?) | Fiber packing (dense vs loose), Fiber orientation (regular vs irregular), and fiber type (collagen vs elastic vs reticular) |
| this type of CT is found in the deep dermis of the skin, non-lactating breasts, and organ capsules | Dense irregular |
| this type of CT is found in tendons and ligaments (minus elastic ligaments) | Dense regular |
