Most important and abundant long-lived CT cells; make CT fibers and ground substance; proliferate in wound healing process, making scar tissue
2 forms of adipocytes
Also called histiocytes; have an abundant “foamy” cytoplasm; essentially perform the “janitor” work
Contain many secretory granules that are basophilic; important in the allergic and inflammation response; metachromatic
“Activated” B lymphocytes that secrete large amounts of antibodies; very numerous in mucosa CT of the gut
Stem cells in CT that have to potential to differentiate into nearly all CT cell’s; very rare in adult tissues; “star-shaped”
3 types of CT fibers
“White fibers”
Function: high tensile strength;
Acidophilic
Types of collagen fibers
The most predominant type of collagen in CT proper
These type of collagen fibers are found in cartilage
Form a delicate network for highly cellular tissues (lymphoid tissues, spleen, bone marrow, etc.)
Reticular fibers need to be stained with silver stains in order to be visualized, thus they are called ___
“Yellow fibers”
Elastic fibers require which kind of stain?
How to classify CTs (i.e., what are the 3 criteria used to classify CT?)
this type of CT is found in the deep dermis of the skin, non-lactating breasts, and organ capsules
this type of CT is found in tendons and ligaments (minus elastic ligaments)
