Connective tissue cells refer to the cells that are found in the subendothelial connective tissue of the intima and in the adventitia, where they surround blood vessels, lymphatics, and nerves. AI generated def
These cells are mononuclear phagocytes that are macrophages with characteristic phagocytic activity producing NaHA, which is excreted into their immediate intercellular matrix environment. The cells are embedded on the edge of the collagen network of the synovial membrane. Rheumatoid tissue is also ...
Electron microscopy of loose, dense regular, dense irregular, and embryonic connective tissue. The fixed and transient cells of connective tissue.
Connective tissue is composed of fibroblasts and other cells and an extracellular matrix (ECM) of various protein fibers, all of which are surrounded by watery ground substance. In all types of connective tissue the extracellular volume exceeds that of the cells. TABLE 5–1 Functions of cells in...
Some tissues have specialized cells that are not found in the others. The matrix in connective tissues gives the tissue its density. When a connective tissue has a high concentration of cells or fibers, it has proportionally a less dense matrix....
Cell Types in Connective Tissue Numerous cell types are found in connective tissue. Fibroblasts, histiocytes, plasma cells, and mast cells are cell types that are found in loose connective tissue. Fibroblast A fibroblast is a connective tissue cell derived from mesenchyme. Fibroblasts produce collagen...
very fine, short collagenous fibers that are highly branched and form a delicate supporting network two categories of cells that make up connective tissue fixed cells and wandering cells fixed cells reside in the tissue for an extended period of time ...

-Fixed macrophages stay in one tissue, but free macrophages migrate throughout the body Microphage -Phagocytic blood cells that participate in non-specific immunity-Smaller than macrophages-Ex: neutrophils and eosinophils Mast Cell -Originate from bone marrow-Fixed: stays in one tissue-Functions as ...
