17
Q

Found in places subject to a lot of mechanical abrasion such as the skin, mouth, esophagus, and vagina

A

Stratified squamous epithelium

18
Q

Rare and hard to identify with light microscopes

A

Stratified cuboidal and stratified columnar epithelia

19
Q

Many cells lie near the base of the tissue, next to the connective tissue, but only a few of these reach the surface of the tissue. Many more nuclei at the base than at the surface. Those that do not reach the surface are columnar in shape.

A

Pseudo-stratified columnar epithelium

20
Q

Stratified type of epithelium cells are cuboidal when the tissue is relaxed, but can become flattened as they get stretched out

A

Transitional epithelium

21
Q

Surface cells are large and relatively clear, while deeper cells are packed more closely together

A

Transitional epithelium

22
Q

Fewer cells but a large amount of space between them(extracellular matrix)- gives tissue its characteristic appearances and functions

A

Connective tissue

23
Q

Composed of ground substance and fibers

A

Extracellular matrix

24
Q

Consists of water with many other molecules dissolved in it(mostly proteins and polysaccharides)

A

Ground substance

25
Q

Large strands of protein which are not soluble in water

A

Fibers of extracellular matrix

26
Q

Collagen fibers, elastic fibers, and reticular fibers

A

Fibers in the extracellular matrix of connective tissue

27
Q

Bundles of the protein collagen

A

Collagen fibers

28
Q

Small groups of collagen

A

Reticular fibers

29
Q

Embryonic connective tissue

A

Mesenchyme

30
Q

Cushions and protects many internal organs

A

Loose areolar connective tissue

31
Q

Loose structure with a lot of extracellular matrix. Many fibers in numerous directions

A

Loose areolar connective tissue

32
Q

Fibers(collagen and elastic) are denser and are not arranged in any particular direction

A

Dense irregular connective tissue

33
Q

Found in tendons and ligaments which must withstand stress in a single direction

A

Dense regular connective tissue

34
Q

Fat tissue

A

Adipose connective tissue

35
Q

Cells of adipose connective tissue are called?

A

Adipocytes

36
Q

Specialized connective tissue that provides flexible support

A

Cartilage

37
Q

3 types of cartilage

A

Hyaline, elastic, and fibrous

38
Q

Collagen fibers are not easily visible and has a smooth glass like appearance

A

Hyaline cartilage

39
Q

Tissue that is living, cellular tissues has a very large number of blood vessels and nerves supporting it

A

Bone tissue

40
Q

Contains large amounts of insoluble calcium salt, making it rigid, is possible to remove this material and make flexible

A

Extracellular matrix of bone tissue

41
Q

Central canal and all of the lamella around it

A

Osteon
