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
