(57 cards)
what are reticular fibers/what produces them
thin, branched structures typically found in lymphatic tissue
produced by fibroblasts (reticular cells)

fibrocye nuclei of dense regular CT

type II collagen
Embryonic CT
umbilical cord, pulp of developing teeth rich in ECM and mesenchymal cells Wharton’s Jelly
name the cell type

plasma cells
loose CT is found
mucosa/subucosa of various organs, surrounding blood vessels, nerves, muscles
Tunica adventitia of BV
label

left down: collagen fibers, elastic fibers, mast cells, ground substance
right arrow: fibroblasts
label arrows

blue: elastin
purple: fibrillin
elastic fibers are formed by
fibroblasts (in skin and tendons), chondroblasts (in elastic cartilage) and smooth muscle cells (in blood vessels and the respiratory tract)
