  Side A   Side B
1
what does connective tissue consist of?
 
individual cells scattered within an extracellular matrix
2
what is the extra-cellular matrix made of?
 
various fibers suspended in a fluid known as ground substance
3
what does ground substance consisnt of
 
water flycosaminoglycansproteoglycansglycoproteins
4
what helps Ground substance exist as either watery liquid or firm solid form
 
chemical composition, amount of tension and temperature
5
what does the thixotropy describe
 
ability of ground substance to become more liquid as a movement and temp of the tissue increases
6
what 3 fibers are suspended in the ground substance
 
collagenreticularelastic
7
what shape is collagen fiber?
 
long , straight, wound like a rope
8
what does the shape confer to the connective tissue?
 
tensile strength and flexibility
9
where are collagen fibers more abundant?
 
tissues that require a strong resistance to force like ligaments and tendons
10
what shape are reticular fribers?
 
thin and branch into tiny nets capable of resisting force in multiple directions
11
what can the reticular fibers do?
 
help hold organs and support structures together
12
what protein is in elastic fiber?
 
elastin
13
how does elastic fiber look?
 
branched and wavy
14
why are they in connective  tissue?
 
so that the tissue can return to original shape after being stratched
15
what so firbroblasts do?
 
produce and secrete proteins that make up the fibers in the extra-cellular matrix
16
what is specific name for fibroblast in the bone? 
 
osteoblasts
17
what is specific name for fibroblast in the cartilage? 
 
chondroblasts
18
give an example of other individual cells found in connective tissue
 
immune cells, like mast cells macrophages , adipocytes
19
give 4 types of connective tissue
 
loosedensefluidsupporting
20
what does the loose connective tissue consist of?
 
high levels of ground substance and fewer fibers adipose tissue and the superficial (just below...
21
what does the dense connective tissue consist of?
 
thicker and stronger. more collagen fibers and less ground substance then loose connective...
22
give example of dense connective tissue
 
ligaments, tendons, joint capsules
23
what does the fluid connective tissue consist of?
 
watery because presence of watery (92%) plasma in exracellular matrix
24
examples of fluid connective tissue
 
blood and lymph
25
what does the supporting  connective tissue consist of?
 
strong solid because additional calcium salts deposited in ground substance
26
examples of supportive connective tissue
 
cartilage and bone
27
connective tissue stores energy in the form of?
 
fat cells (adipose)
28
give the names of the types of synovial joints
 
ball and sockethingepivotcondyloidsaddle gliding
29
what are cadavers?
 
preserved human bodies used for scientific study
30
list the  8 functions of connective tissue

31
what are proteoglycans made of?
 
core protein and  gags ( glycosaminoglycans)
32
name the 4 types of polysaccharides found in ground substance
 
 _GAGs -glycosaminoglycans(attract water and make g.s more gel like_hyaluronic acid 9viscous...
33
what are the types of proteins in ground substance
 
 proteoglycans and adhesion proteins(e.g fibronectin,binds to both collagen and ground...
34
give location of areolar loose tissue
 
between structures
35
give location of adipose loose tissue
 
sub cutaneous fat and e.g around kidneys
36
give location of reticular loose tissue
 
blood vessels and smooth tissue
37
give location of dense regular tissue
 
ligaments and tendons and retinacula
38
give location of dense irregular tissue
 
fasciae e.g abdomen
39
give location of dense elastic tissue
 
some ligaments of vertebral column and lung tissue
40
where would you find some smooth muscle cells
 
bronchial walls or arteries
41
what is surrounding smooth muscle cells?
 
blue stained collagen separating one bundle of cells from its neighbour
42
what does the retinacula do?
 
retains tendons in position (dense regular)
