Answer 1

1. fibrous proteins –collagen + elastin
2. Ground substance: proteglycans

Question 2

Answer 3

Bends, springs (recoil + come back)

Question 4

Suffix used to identify cell functions:
-Blast…

Answer 4

(Germ) form the matrix

Question 5

Suffix used to identify cell functions:
-cyte…

Answer 5

(Cell) maintain the matrix

Question 6

Suffix used to identify cell functions:
-clast…

Answer 6

(Break) break the matrix down

Question 7

Areolar Tissue cells

Answer 7

Fibroblasts

Question 8

What is the ground substance in areolar tissue cells?

Answer 8

Hyaluronic acid

Question 9

Adipose tissue cells

Answer 9

Adipocytes (fat)

Question 10

Where are areolar tissues found?

Answer 10

Under all epithelia, between muscles, nerves, + blood vessels

Question 11

Adipose tissue location

Answer 11

All over body

Question 12

Dense regular tissue cells

Answer 12

Fiberblasts

Question 13

Dense regular tissue location

Answer 13

Tendons + ligaments

Question 14

Dense irregular tissue cells

Answer 14

Fiberblasts

Question 15

Dense irregular tissue location

Answer 15

Dermis of skin (mid layer of skin)

Question 16

Cartilage features (3)

Answer 16

1. cells are chondrocytes
2. no blood vessels (diffusion brings nutrients + removes waste, heals slowly)
3. strength depends on fibers present, density, + alignment
