Connective Tissue Proper Flashcards
(35 cards)
Loose connective tissue has more and fewer
Ground substance, fewer fibers
Dense connective tissue has more, and less
Fibers, ground substance
Fibroblasts
Most abundant cell type
Found in all types of connective tissue proper
Secretes proteins and hyaluronan (cellular cement)
Fibrocytes (maintain)
Maintain connective tissue
Adipocytes
Fat cells
Each cell stores a single, large fat droplet
Mesenchymal cells are
Stem cells
Mesenchymalcells respond to
Injury or infection
Melanocytes synthesize and store
Melanin
Macrophages are
Large phagocyticcells of the immune system
Macrophages engulf
Pathogens and damaged cells
Fixed and free macrophages
Stay in tissue, migrate
Mast cells stimulate (cause)
Inflammation after injury or infection
Mast cells release
Histamine and heparin
Lymphocytes (migrate)
Migrate through the body
Lymphocytes may develop (into)
Into plasma cells
Plasma cells produce
Antibodies
Microphages are
Phagocytes blood cells
Microphages are attracted to
Signals from macrophages and mast cells
Collagen fibers are (characteristics)
Long, straight, unbranched
Strong, flexible
Collagen fibers resist
Force in one direction
Collagen fibers are common
In connective tissue proper
In tendons, and ligaments
Reticular fibers (characteristics)
Strong, flexible
Reticular fibers (characteristics)
Strong, flexible
Reticular fibers resist forces
In many directions
