Q

Bronchi and uterine tube lining is what?

A

Ciliated

17
Q

What is keratin?

A

A hard protein, designed for protection

18
Q

Stratified squamous epithelium keratinized

A

-many layers of flat cells
-Found in epidermis of skin

19
Q

Stratified squamous epithelium non keratinized

A

Same characteristics as keratinized, except upper layers of cells don’t die and aren’t filled with keratin.
Visible nuclei
Found in lining of esophagus, vagina, mouth.

20
Q

Pseudostratified columnar epithelium

A

Cells only in 1 layer, but are different heights.
Makes tissue appear stratified but it is not.
Very tightly packed together

21
Q

Where are pseudostratified columnar epithelium found?

A

Lining in trachea ( contains goblet cells and possess cilia.)
Lining in the male reproductive ducts and ducts of large glands.

22
Q

transitional epithelium

A

stratified tissue
cells slide past each other to allow stretching of the tissue layer.

23
Q

where is transitional epithelium found?

A

lining of the urinary bladder, ureters, urethra

24
Q

connective tissue

A

binds, supports, protects, and fills spaces.

25
Q

what is the space between the cells occupied by?

A

the matrix

26
Q

what is the matrix

A

it is a substance produced and secreted by connective tissue cells.

27
Q

what fibers does the matrix consist of?

A

collagen, elastic, and recticular.

28
Q

connective tissue proper

A

areolar, dense irregular, dense regular, reticular, adipose, elastic

29
Q

specialized connective tissue

A

hyaline cartilage, fibrocartilage, elastic cartilage, compact bone, cancellous, blood

30
Q

areolar (loose) connective tissue

A

gel like matrix
cells include fibroblasts
found around capillary networks

31
Q

dense irregular connective tissue

A

matrix consists of collagen fibers
main cell type is fibroblast
found in reticular layer of dermis, wall of digestive tract

32
Q

dense regular connective tissue

A

matrix contains parallel bundles of collagen fibers
main cell is fibroblast
forms ligaments and tendons

33
Q

reticular connective tissue

A

matrix consists of reticular fibers
main cell type is reticular cells
found in lymph nodes, spleen, and bone marrow

34
Q

adipose tissue

A

composed of adipocytes
sparse matrix and few fibers
protective padding, insulation, energy storage
found in subQ layer of skin, around kidneys, eyeballs, heart, breasts, abdominal cavity

35
Q

elastic connective tissue

A

modified dense regular connective tissue
allows recoil of tissue
found in walls of large arteries, walls of bronchial tubes

36
Q

hyaline cartilage

A

very firm matrix
functions to reduce friction between bones
contain chondrocytes called lacunae
avascular tissue
found in the ends of long bones, costal cartilage, cartilage of nose, trachea, and larynx

37
Q

fibrocartilage

A

matrix contains collagen fibers
found in intervertebral discs, pubic symphysis, and menisci of knee
