Varys in structure and function
Highly vascularised and well nourished.
Cell adhesion mechanism
Replication and repair

Question 12

Answer 12

Specialised cells 
- Fibroblasts and osteocytes 
Protein Fibres 
- Collagen
Ground substances 
- Fills all spaces between cell fibres and ground substances MATRIX 
Largest volume of connective tissue

Question 13

What components consist in the supporting of connective tissue?

Answer 13

Bone and cartilage

Question 14

What components consist in the supporting of fluid in the C.T?

Answer 14

Blood and Lymph

Question 15

What components consist in the supporting of THE PROPER in the C.T?

Answer 15

Loose and dense C.T

Question 16

Name the 5 supporting cells in connective tissues?

Answer 16

• Fibroblasts
• Chondrocytes
• Osteocytes
• Myofibroblasts
• adipocytes

Question 17

What are the 3 connective tissue fibres and describe them?

Answer 17

•Collagen
Long, straight, branched, strong, flexible

•Reticular
Thinner than collagen, forms branching interwoven
network

•Elastic
Branched, wavy, after stretching returns to normal

Question 18

Define the embryonic classification of C.T?

Answer 18

During development, migrates and interacts with other tissues to form organs

Some mesenchyme persists past embryonic period:
Undifferentiated cells around blood vessels (fibroblasts) which repair the vessel.

Question 19

Define the connective tissue proper classification?

Answer 19

Large spindle shaped cell (fibroblast).

• Produces collagen, elastic and reticular fibres.
• Loose flexible matrix.

•Six basic types distinguished by matrix, and type and arrangement of fibres.

Question 20

Define Loose C.T?

Answer 20

Flexible strength in all directions (skin)

Question 21

Define Dense Regular C.T?

Answer 21

Densely packed collagen fibres parallel to direction of force (tendons and ligaments)

Question 22

Define Dense Irregular C.T?

Answer 22

Densely packed collagen fibres (dermis of skin)

Question 23

Define elastic C.T?

Answer 23

Elastic fibres that can stretch 1.5 times and return.

walls of large arteries

Question 24

Define Reticular C.T?

Answer 24

Jellylike matrix (forms framework of organs such as liver and spleen)

Question 25

Define Adipose C.T?

Answer 25

Cells store fat droplets. Acts as food reserve, protects organs and insulator.

Question 26

Define the cartlidage classification?

Answer 26

Cell Chondrocyte Semisolid matrix with marked elastic poperties * Supportive and protective CT frequently associated with bone * Avascular (difficult to heal) * Three types – based on type and amount of fibres embedded within matrix

Question 27

What is the location and function of hyaline cartridge?

Answer 27

Location- Between the tips of ribs and bones of sternum covers synovial joints Function- Stiff but flexible support and reduces friction between bony surfaces

Question 28

What is the location and function of elastic cartridge?

Answer 28

Location- Auricle of the external ear and the epiglottis auditory canal and cuniform cartridges of the larynx. Function- Provides support and tolerates distortion without damage

Question 29

What is the location and function of fibrocartridge?

Answer 29

Location- Pads within the knee joint between the pubic bones of pelvis. Function- Results compression prevents bone to bone contact

Question 30

What cells are within the vascular connective tissue?

Answer 30

Erythrocytes Leukocytes Thrombocytes (platelets) * Highly specialised - viscous * Liquid plasma matrix RBCS WBCS - Monocytes - Lymphocytes - Eosinophils - Microphages - Neutrophils - Basophils PLATELETS
