1

What is the group of connective tissue that is avascular

Cartilage

2

What embryonic derivative does all connective tissue arise from

Mesoderm which differentiates further into mesenchymal stem cell

3

What are the criteria used to classify connective tissue

Matrix:
--Ground Substance
--Fibres

Cell Type

4

What makes up the ground substance of connective tissue

Proteoglycans
Multiadhesive glycoproteins
Glycosaminoglycans (GAGs)

5

What is the structure of collagen fibres

Have a binding pattern

6

What cells make collagen fibres

Fibroblasts, Chondrocytes, Osteoblasts

7

What protein makes up elastic fibres

Elastin

8

What is the structure of elastic fibres

Braching pattern - form a 3D pattern
Random coiling

9

What cells synthesise elastic fibres

fibroblasts

10

What is the structure of reticular fibres

Makes a mesh (stroma)
Branch, but do not bundle

11

What type of fibre requires a special stain? What is this stain called?

Reticular fibre
Needs a argyrophilic (silver stain)

12

What can mesenchyme also be called

primitive connective tissue

13

What makes up primitive CT (ground substance, fibres, cells)?

Viscous ground substance
Fine and sparse collagen and reticular
Spindle-shaped cells with processes

14

What makes up primitive CT (ground substance, fibres, cells)?

Gelatin-like ground substance
Thin, whispy collagen fibres
Spindle-shaped cells

15

What can loose CT also be called

Areolar CT

16

What makes up primitive CT (ground substance, fibres, cells)?

Abundant viscous ground substance

Serosa

18

What makes up the mucosa

Mucus epithelium
Lamina propria
Muscularis mucosae

19

What is lamina propria made of

Loose (areolar) CT

20

What makes up the submucosa

Duct from gland
Gland in submuscosa

21

Where in the layers of hollow organs is dense irregular CT found

Submucosa

22

What makes up the muscularis

Circular muscle layer
Longitudinal muscle layer

23

24

What are the two types of dense CT

Regular or Irregular

25

What are the cells that make up dense CT

fibroblasts

26

What makes up dense irregular CT (ground substance, fibres, cells)?

Abundant collagen fibres
Little ground substance
Sparse cells

27

Where is dense irregular CT found

Submucosa (hollow organs)
Dermis of skin

28

What makes up dense regular CT (ground substance, fibres, cells)?

Dense, parallel, tightly packed collagen fibres
Little ground substance
Cells (eg. tendinocytes) aligned with fibres

29

Where is dense regular found

Tendons, ligaments, Aponeoroses

30

What is the function of dense irregular CT

REsistance to stretching, distension and tearing

31

What is the function of dense regular CT

Provides maximum strength.

32

What are the types of collagen and what are they associated with

Type I: Skin, hair, nails, bone, ligaments, organs
Type II: Cartilage
Type III: Reticulate

33

What do fibroblasts synthesise

Collagen, elastic and reticular fibres

34

Kidney-shaped nucleus
Lysosomes (granules)

35

What is identifyable about a mast cell

Granules - heparin (an anticoagulant) and histamine
Big and roundish

36

What are mesothelial cells

Cells that line body's serous cavities and internal organs. Provides a non-adhesive surface for protection
