2. Elastic cartilage
3. Fibrocartilage

Question 13

Bone tissue

Answer 13

1. Compact bone

2. Spongy bone

Question 14

Areolar Connective Tissue (Loose)

Answer 14

Underlies almost all of the epithelia and surrounds almost all the small nerves and blood vessels
Gel-like matrix, wraps and cushions organs
1. Supports and binds tissues
2. Holds body fluids
3. Defends against infections
4. Stores nutrients as fats

Question 15

Adipose Connective tissue (Loose)

Answer 15

crowded with fat cells, occur mostly in the hypodermis
Matrix is the same as areolar but very sparse
Provides reserve food fuel, insulates, supports and protects organs
Around kidneys, eyeballs. breasts

Question 16

Reticular Connective tissue (Loose)

Answer 16

Network of reticular fibers
Supports other cell types like white blood cells
Lymphoid organs

Question 17

Irregular Connective tissue (Dense)

Answer 17

Irregularly arranged collagen fibers
can withstand tension in many directions
fibrorus layer in joints

Question 18

Regular Connective tissue (Dense)

Answer 18

Parallel collagen fibers, major cell type is fibroblast
attaches muscles to bones and muscles
tendons, ligaments

Question 19

Elastic Connective tissues (Dense)

Answer 19

containing high proportion of elastic fibers
can be stretched and returns to normal shape
walls of large arteries

Question 20

Hyaline Cartilage

Answer 20

firm matrix, collagen fibers

covers the ends of long bones in joints, in ribs, nose, trachea and larynx

Question 21

Elastic Cartilage

Answer 21

similar to hyaline, but more elastic fibers in matrix

EAR

Question 22

Fibrocartilage Cartilage

Answer 22

matrix similar to hyaline but less firm

intervertebral discs, pubic symphysis, discs of knee joint

Question 23

Osseous Bone Tissue

Answer 23

hard, calcified matrix with many collagen fibers

in the bones
