20
Q

mast cells

A

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

21
Q

fibers of CTP

A

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

22
Q

Collagen fibers

A

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

23
Q

reticular fibers

A

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

24
Q

Elastic fibers

A

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

25
Q

Ground substance of CTP

A

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

26
Q

Categories of CTP

A

Loose ct
dense ct

27
Q

loose ct

A

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

28
Q

Areolar

A

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

29
Q

Adipose tissues

A

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

30
Q

Reticular tissue

A

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

31
Q

dense ct

A

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

32
Q

dense regular ct

A

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)

33
Q

Elastic tissue

A

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

34
Q

Dense irregular connective tissue

A

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

35
Q

fluid connective tissues

A

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

36
Q

blood

A

fluid content is plasma
formed elements
rbc
wbc
platelets

37
Q

lymph

A

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

38
Q

cartilage

A

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

38
Q

supportive ct

A

support soft tissue and body weight
bone and cartilage

38
Q

types of cartilage

A

hyaline
elastic
fibro

39
Q

bone

A

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

40
Q

hyaline

A

tough, flexible support
reduces friction in joints
translucent mix
no predominant fibers
trachea

41
Q

elastic cartilage

A

flexible support
tightly packed elastic fiber
external ear and epiglottis

41
Q

fibrocartilage

A

resists compression
prevets bone to bone contacts
limits movement
very dense collagen fibers
knee pads

42
Q

bone osseous tissue

A

strong calcium deposits
resists shattering
flexible collagen

43
Q

fascia

A

body’s connective tissue framework
layers and wrappings that support and surroudn porgans
provides routes fro blood vessels, lymphatics and nerves
3 layers

44
Q

3 layers of fascia

A

superficial
deep
subserous fascia
