Ch 5: Connective Tissues

Question 1

What are the types of connective tissue?

Answer 1

1. Loose Connective Tissue
2. Dense Connective Tissue
3. Cartilage
4. Bone
5. Blood

Question 2

What are the types of Loose Connective Tissue?

Answer 2

Areolar
Adipose
Reticular

Question 3

What are the types of Dense Connective Tissue?

Answer 3

Dense Regular
Dense Irregular
Elastic Connective Tissue

Question 4

What are the types of Cartilage?

Answer 4

Hyaline
Fibrocartilage
Elastic

Question 5

What are the characteristics of Areolar Connective Tissue?

Answer 5

Collagen stained pink with lots of open space.

Dark Fibroblasts which synthesize collagen fibers

Loose space allows macrophages in

Question 6

What are the characteristics of Adipose Tissue?

Answer 6

Adipocytes (Fat Tissue)

Cushioning or like packing material

Secrete some hormones

Question 7

What are the characteristics of Reticular Connective tissue?

Answer 7

For structure/framework of stroma

Can stain Purple or Brown

Question 8

What are the characteristics of Dense Regular Connective Tissue?

Answer 8

Regularly organized fibers tightly packed in one direction

Resists stretch in longitudinal direction (not perpindicular)

Found in ligaments (bone to bone) and tendons (bone to muscle)

Question 9

What are the characteristics of Dense Irregular Connective tissue?

Answer 9

Tightly packed fibers in all directions

• Resists being pulled apart in all directions
• Have this type of tissue where you don’t want ANY stretching to occur

Question 10

What are the characteristics of Dense Elastic Connective Tissue?

Answer 10

Regularly organized tissues in one direction but not as tightly packed as Dense Regular

Found where you need stretch/recoil (elasticity) such as in the heart or aorta

Pink stain is collagen, Elastin fibers stain dark purple squiggly lines

Question 11

What are the characteristics of Hyaline Cartilage?

Answer 11

Purplish Stain found underneath epithelial tissue

Found in between bones, trachea, nose

Does not regenerate

Contains alot of water so good at resisting compression

Question 12

What are the characteristics of Fibrocartilage?

Answer 12

Contains Collagen + Cartilage

Usually stains blue

Found in places where you need to resist Pulling and Compression

• Like vertebral column
• Cartilaginous part can retain water (compression)

Question 13

What are the characteristics of Elastic Cartilage?

Answer 13

Cartilage that can stretch/recoil (elasticity)

Continues to grow throughout life

Think Ears, epiglottis

Question 14

What type of cell synthesizes collagen/reticular/elastin fibers? What kind of cell synthesizes cartilage?

Answer 14

Collagen/Reticular/Elastin Fibers: Fibroblast

Cartilage: Chondrocyte

Question 15

What are membranes? What are the types?

Answer 15

Composed of epithelium + connective tissue

Mucous Membranes (Mucosa)
Serous Membranes (Serosa)
Cutaneous Membranes (Skin)
Synovial Membranes (not real membrane)

Question 16

What is a mucous membrane (mucosa)?

Answer 16

Lining of internal tract with opening to outside world

-Like digestive or respiratory tract

Question 17

What is a Serous membrane (serosa)?

Answer 17

Lining of internal body cavity not open to outside world
-Lines cavity and lines outside of organ

Parietal layer: lines wall of cavity
Visceral layer: lines surface of organ in cavity

Question 18

What is a Cutaneous membrane (skin)?

Answer 18

In between layers

Question 19

What is a Synovial membrane (not real membrane)?

Answer 19

Encapsulates any freely movable joint

-Filled with synovial fluid made by synoviocytes

Question 20

What is the endothelium and mesothelium?

Answer 20

Endothelium - epithelium inside blood vessels

Mesothelium - epithelium of serosa
