Answer 6

transport
blood and lymph

Question 7

supportive connective

structural strength
bone and cartilage

Question 8

CT proper make up

Answer 8

cells
matrix

Question 9

cells of connective tissue proper

Answer 9

migratory
permanent residence

Question 10

migratory cells

Answer 10

lymphocytes
macrophage
microphage
mast cells

Question 11

permanent residence cells

Answer 11

fibroblasts
adipocytes
mesenchymal cells
melanocytes

Question 12

Fibroblasts

Answer 12

most abundant
found in all CTP
secrete protein and hyaluronan

Question 13

adipocytes

Answer 13

fat cells
each stores a single large fat droplet

Question 14

mesenchymal

Answer 14

stem cell
divides to compensate for injury unlike others

Question 15

melanocytes

Answer 15

synthesize and store brown pigment

Question 16

lymphocytes

Answer 16

m
specialized immune cells
t and b lymphocytes
b lymphocytes may develop to plasma and produce antibodies

Question 17

Macrophage

Answer 17

m
large amoeba like cells
part of immune system
engulfs pathogens and damaged cells

Question 18

2 conditions of macrophage

Answer 18

free macrophages migrate like monocytes in blood

fixed macrophages stay in tissue like kpuffer cells in liver

Question 19

microphage

Answer 19

small phagocytic blood cells
respond to signal from macrophage and mast cells
eg. nautrophils

Question 20

mast cells

Answer 20

stimulate inflammation after injury/infection
granules release histamine + heparin
basophils are mast cells carried by blood

Question 21

fibers of CTP

Answer 21

Collagen fibers
reticular fibers
elastic fibers
(all formed by fibroblasts)

Question 22

Collagen fibers

Answer 22

most common fibers in CTP
long straight and unbranched
strong and flexible
bundle of fibrous protein strands
resist force in 1 direction
tendons and ligaments

Question 23

reticular fibers

Answer 23

network of interwoven fibers (stoma)
strong and flexible
resist in many directions
stabilize functional cells and structures
Sheath around organs

Question 24

Elastic fibers

Answer 24

Contain elastin
branched and wavy
flexible, return to original shape
Elastic ligaments of vertebrae and ear lobe

Question 25

Ground substance of CTP

Answer 25

Fill space between cells clear and colourless vicious and dense - slows down pathogens

Question 26

Categories of CTP

Answer 26

Loose ct dense ct

Question 27

loose ct

Answer 27

more ground substance less fibres packing materials of body areolar adipose and reticular

Question 28

Areolar

Answer 28

least specialized open framework vicious ground substance elastic absorb shock holds blood vessels and capillary beds eg subcutaneous tissue (under skin)

Question 29

Adipose tissues

Answer 29

main cell adipocytes provides padding, insulation, energy storage deep in skin of side breast and butt

Question 30

Reticular tissue

Answer 30

COmplex, 3d network reticular fibers(stroma) support functional cells (parenchyma) reticular organs spleen, lymph nodes, bone marrow, kidneys

Question 31

dense ct

Answer 31

tightly packed w high number of collagen or elastic fibers (collagenous tissues) regular and irregular ct

Question 32

dense regular ct

Answer 32

attachment and stabilization tightly packed parallel collagen fibers tendons (attach muscles to bones) ligaments (connect bone to bone) aponeuroses (ct sheets attached to flat muscles)

Question 33

Elastic tissue

Answer 33

sub type of dense regular ct made mainly of elastic fibers elastic ligaments

Question 34

Dense irregular connective tissue

Answer 34

strength in many directions interwoven network of collagen fibers perichondrium and periosteum

Question 35

fluid connective tissues

Answer 35

blood and lymph watery mix pf dissolved proteins specific cell types/formed elements

Question 36

blood

Answer 36

fluid content is plasma formed elements rbc wbc platelets

Question 37

lymph

Answer 37

collected from interstitial space monitored by immunse system transported by lymphatic vessels returned to venous system

Question 38

cartilage

Answer 38

gel like ground substance between bones for shock absorbtion and protection no blood vessels

Question 38

supportive ct

Answer 38

support soft tissue and body weight bone and cartilage

Question 38

types of cartilage

Answer 38

hyaline elastic fibro

Question 39

bone

Answer 39

calcified rigid by calcium salts/minerals for weight support rich blood supply

Question 40
