Answer 5

cubelike

Question 6

columnar

Answer 6

elongated

Question 7

simple squamous location

Answer 7

air sac
inside vessels
wall of capillaries

Question 8

simple squamous

Answer 8

substances pass easily through,
site of diffusion&filtration
thin /delicate
easily damaged

Question 9

simple cuboidal location

Answer 9

lines follicles of thyroid gland
covers ovaries
lines kidney,tubules, ducts of s.glands

Question 10

simple columnar

Answer 10

nuclei same level (near basement membrane)
sometimes: ciliated.
absorption (have microvilli)
thick tissue/protect

Question 11

simple columnar location

Answer 11

move egg cells (w/cilia)

(w/o cilia) uterus, part digestive tract, secrete digestive fluid, absords nutients

goblet cell

Question 12

pseudo stratified

Answer 12

commonly: cilia

goblet cell

Question 13

pseudostratifies location

Answer 13

respiratory

Question 14

stratified squamous

Answer 14

thick
free surface: squamous (old)
basement: cuboidal/columnar

Question 15

stratified squamous location

Answer 15

epidermis, oral cavity, esophagus , vagina, anal

Question 16

stratified columnar

Answer 16

free surface: elongated

basement: cuboidal

Question 17

stratified columnar location

Answer 17

male urethra, parts of pharynx

Question 18

transitional

Answer 18

contract: cuboidal
stretch: thinner

smaller at the bottom near basal

Question 19

transitional location

Answer 19

bladder, ureter, part urethra, barrier on urinary tract

Question 20

connective tissue

Answer 20

• most abundant tissue by weight
• cells far apart
• has extracellular matrix btw cells
• usually divide
• vary degree of vascularity, most of the time, usually, has blood vessels

Question 21

cell types in connective tissue

Answer 21

fibroblast (fixed): large,star shaped, produce fibers into matrix

macrophages (wandering):
attached to fibers but can b detached, phagocytosis, immunity

mast(fixed): releases heparin (prevent clotting) and histamine (dilates blood vessels)

Question 22

extracellular matrix

Answer 22

fibers and ground substance

ground sub; binds, support, provides medium for substance transfer btw blood and cells

Question 23

connective tissue fibers

Answer 23

collagenous
elastic
reticular

Question 24

collagenous fibers

Answer 24

thick, long parallel bundles, flexible slightly elastic, great tensile (pulling)

Question 25

elastic

Answer 25

made of elastin, weaker than collagenous, very elastic

Question 26

Reticular

Answer 26

thin collagenous fibers

Question 27

Loose/Areolar | CT

Answer 27

thin membrane cell: fibroblast fibers: little collagenous&elastic function: bind skin to underlying organs and fill space btw muscle. vascular. under epithelium

Question 28

adipose

Answer 28

function: cushion joint, kidney, insulate beneath skin, store flat in cytoplasm, eyeball, btw muscle, heart surface looks like fibroblast w/o fat

Question 29

reticular

Answer 29

thin collagenous fibers function: provide framework of certain internal organs location: liver, spleen, lymphatic

Question 30

Dense

Answer 30

abundant thick closely packed collagenous, some elastic, few cells (fibroblast)

Question 31

dense regular

Answer 31

withstand puling, poor blood supply/slow repair binds body part together/ surrounds joint Tendon cartilage

Question 32

irregular dense

Answer 32

thick, interwoven, randomly organized fibers. sustain tension from all direction dermis

Question 33

elastic

Answer 33

parallel elastic fibers , collagenous and fibroblast btw them attachments btw bones of spinal, layers btw wall of s. hollow internal organs

Question 34

cartilage

Answer 34

matrix: mostly collagenous, no direct blood supply. perichondrium covers cartilage (has blood)

Question 35

hyaline cartilage

Answer 35

fine collagenous poor regeneration end of bones, nose, respiratory, development

Question 36

elastic cartilage

Answer 36

dense elastic, more flexible than hyaline, | external ears, s.larynx

Question 37

fibrocartilage

Answer 37

many large collagenous fibers, shock absorber | spinal, cushion bone in knee and pelvic

Question 38

bone

Answer 38

mineral salt, collagenous abundant, layers: lamellae osteon, whole circle, central canal: blood vessle

Question 39

blood

Answer 39

matrix: plasma red blood: transport gasses (vessels) white blood: fight infection (migrate through capillary walls) platelet: cellular fragment, help blood clotting

Question 40

muscle tissues

Answer 40

elongated shape, contract, moves body part

Question 41

cardiac

Answer 41

``` branched intercalated disc striated single nuclei no regenerate ```

Question 42

smooth

Answer 42

``` nonstriated leaf shaped walls of hollo organ single nucleus highest regenerate ```

Question 43

skeletal

Answer 43

voluntary limited regenerate multiple nuclei attached to bones

Question 44

nervous tissue

Answer 44

neuroglia: support and binds tissue phagocytosis help supply nutrients to neurons
