fixed in ct.

principle cell

arise from mesenchyme cells

responsible for synthesis of collagen, reticular fibers, and ALL ground substance

spindle shaped with eosinphilic tapered cytoplasmic extensions

irregular and branched

spindled shaped and less pronounced

contain 1 or 2 nuclei

hybrid btwn fibroblast and smooth muscle clell

found in areas of wound healing

Fnct: wound contraction and periodontal ligament--> tooth eruption

MNPC

arise from moncytes

long lived

fusion of macrophages forms MN giant cells=can phagocytoze large foreign bodies

function in opsinisation aswell

1) coat w. opsonin

3) cell receptors rcognize coat

4) phagocytosis

5) fusion w/ lysosome

mature B-cells. transisent macropgae. found in areas where bacteria are most likely to penetrate

Basophilic cytoplasm, well developed golgi

clock face arrangement

alternating euchromatin and heterchromatin

Fixed macrophage found in Bone marrow.

small centrally located nucleus

metachromatic staining because of lots of gags.

pericyte = perivascualr. found near smooth muscle cells.

if sm is damaged it may diff. into one

arises fom mesenchymal cells

1. brown multlocular

2. white unicellular

adipocyte .found in fetal and new borns--> up to 10 years. lots of cytochromes--> multicolored mitochondria. many fat droplets
