Connective Tissue

Question 1

4 main types of connective tissue?

Answer 1

Connective Tissue Proper (loose + dense)
Cartilage
Bone
Liquid

Question 2

7 functions of connective tissue?

Answer 2

• Enclosing + Separating Tissue
• Connecting tissues
• Supporting / moving body parts
• Storing compounds
• Cushioning / insulating
• Transporting
• Protecting

Question 3

3 aspects of extracellular matrix?

Answer 3

Ground substance
Fibres: Collagen / Elastic / Reticular
Fluid

Question 4

Examples of ‘blast’ cells + What they do?

Answer 4

Osteoblasts
Chondroblasts
Fibroblasts
Hematopoietic stem cells

They produce fibres and the ECM

Question 5

Enclosing + separating tissue examples?

Answer 5

muscles - arteries - veins - nerves

remember blood is connective tissue, ^ enclose

Question 6

Connecting tissues examples?

Answer 6

Tendons (muscles to bones)

Ligaments (Bone to bone)

Question 7

Supporting / moving body parts example?

Answer 7

Cartilage (supports joint movement)

Question 8

Storing compounds examples?

Answer 8

Bone (stores calcium + phosphate)
Adipose tissue (high energy molecules)

Question 9

Cushioning / insulating example?

Answer 9

Adipose tissue (cushions tissues & organs)

Question 10

Transporting example?

Answer 10

Blood (nutrients, minerals, enzymes, hormones, gases, immune system cells)

Question 11

Protecting example?

Answer 11

Bone (protect structure)
Immune cells (pathogens + toxins)

Question 12

3 types of loose proper CT

Answer 12

Areolar - Adipose - Reticular

Question 13

What connective tissue has a lack of collagen?

Answer 13

Reticular loose tissue
Adipose loose tissue
Elastic dense tissue
Hyalin cartilage

Question 14

3 types of dense proper CT

Answer 14

Regular - Irregular - Elastic

Question 15

Describe areolar loose tissue?

Answer 15

Function: strength, elasticity + support
Structure: lots of collagen, elastin + reticular fibres
Location: skin - around blood vessels - mucous membranes

Question 16

Describe adipose loose tissue?

Answer 16

Function: protection - insulation - energy store
Structure: mainly adipocytes
Location: around organs - beneath skin (insulation)

Question 17

Describe reticular loose tissue?

Answer 17

Function: The fibers form a soft skeleton (stroma) to support the lymphoid organs (lymph node stromal cells, red bone marrow, and spleen)
Structure: reticular fibres - lack of collagen
Location: gut - liver - spleen - bone marrow

Question 18

Examples of ‘cyte’ cells + What they do?

Answer 18

Osteocytes - Chondrocytes - Fibrocytes - erythrocytes - leukocytes - thrombocytes

Maintain the matrix that the blasts (themselves in their immature state) have produced

Question 19

Describe regular dense tissue?

Answer 19

Function: Strength + support (single direction)
Structure: Lots of collagen (uniform) & fibroblasts
Location: ligaments, tendons

Question 20

Describe irregular dense tissue?

Answer 20

Function: Strength + support (all directions)
Structure: Lots of collagen (random assortment) & fibroblasts
Location: Between organs, dermis of skin, periosteum of bone

Question 21

Describe elastic dense tissue?

Answer 21

Function: Strength + recoil
Structure: Lots of elastin + fibroblasts
Location: Heart + lungs (consider the function)

Question 22

3 types of cartilage?

Answer 22

Fibro - Hyalin - Elastic

Question 23

Describe Fibro cartilage?

Answer 23

Function: Support + fusion (connect bones)
Structure: Chondrocytes within collagen fibres
Location: Skull sutures (fibrous joint)

Question 24

Describe Hyalin cartilage?

Answer 24

Function: Shock absorption
Structure: Chondrocytes with few collagen fibres
Location: Bone, trachea

Question 25

Describe Elastic cartilage?

Answer 25

Function: Strength + elasticity
Structure: Chondrocytes + elastic fibres
Location: Larynx, ear
