Q

Similarities between connective tissues

A

1). Common origin (mesenchyme, fluid/loose embryonic tissue)
2). Diff. degrees of vascularity/blood flow (e.g. cartilage = avascular)
3). Mostly composed of inert extracellular matrix

Q

What is the extracellular matrix composed of?

A

1). Ground substance- fills in spaces between cells
2). Fibers- provide support

Q

Types of fibers

A

1). Collagen- tough and flexible, part of the skin
2). Elastic fiber- long and thin, snap it back in place, found in blood vessel walls/skin
3). Reticular fiber- used to protect organs, “fuzzy nets”

16
Q

Elastic cartilage

A

Loaded w/ collegen fibers, found in places where strength & stretchability are needed (larynx, ears, etc.)

17
Q

Fibrocartilage

A

shock absorbers, good at withstanding lots of pressure, vertebral discs and knee joints

18
Q

Draw areolar tissue

A

ground substance, elastic fibers (thin), collagen fibers (thick), fibroblasts (immature fiber cells)

19
Q

Draw adipose tissue

A

nucleus, adipocyte, cell membrane

20
Q

Draw reticular tissue

A

fibroblasts, reticular fibers, white blood cells

21
Q

Draw dense regular and irregular tissue

A

fibroblasts, collagen fibers, regular = strong in one direction, irregular = strength in all directions

22
Q

Draw hyaline cartilage

A

nucleus, lacuna, chondrocyte, extracellular matrix

23
Q

Draw elastic cartilage

A

extracellular matrix, nucleus, lacuna, chondrocyte, elastic fibers

24
Q

Draw fibrocartilage

A

chondrocyte, nucleus, collagen fiber, ground substance

25
Q

Fibroblast

A

immature baby fiber cells, most common, produces fibers

26
Q

Histiocytes

A

mature cells, macrophages (eats things) of connective tissue, protection

27
Q

Leukocytes

A

mature white blood cells, reside in connective tissues, reacts against foreign matter

28
Q

Plasma cells

A

produces antibodies

29
Q

Mast cells

A

produces heparin (anticoagulant) & histimine (released during infection) found near blood vessels

30
Q

Adipocytes

A

mature fat cells, found in adipose tissue
