Section 3

Question 1

Describe fibrous.

Answer 1

Has greatest tensile strength, can bear a lot of pressure without tearing. (Found between vertebrae)

Question 2

Describe elastic cartilage.

Answer 2

Has elastic fibers, if it’s stretched it goes back into shape

Question 3

Describe hyaline cartilage.

Answer 3

Milky white; most common is articular cartilage at the end of long bones

Question 4

What’s a chrondrocyte?

Answer 4

Cartilage cell

Question 5

3 reasons cartilage resembles bone.

Answer 5

1. There’s more intercellular material than cells (chondrocytes- cartilage cells)
2. Abundance of collagen fibers to help reinforce
3. The chondrocytes are also located in the lacunae

Question 6

3 reasons cartilage differs from bone.

Answer 6

1. The matrix is a firm gel, thus its flexible
2. No blood vessels penetrate the matrix
3. O2 and nutrients reach the chondrocytes by diffusion

Question 7

What are the two main parts of the skeleton?

Answer 7

1. Axial skeleton

2. Appendicular skeleton

Question 8

Describe axial skeleton.

Answer 8

Keeps body upright. Includes skull, rib cage, sternum, vertebral column and hyoid bone. (Hyoid bone is the only bone a doesn’t articulate with another bone; found in neck)

Question 9

The appendicular system is?

Answer 9

Skelton of appendages (arms and legs)

Question 10

What has great tensile strength, can bear a lot of pressure without tearing ( found in vertebrae )

Answer 10

Fibrous cartilage

Question 11

What has elastic fibers, so if stretched it goes back into shape?

Answer 11

Elastic cartilage

Question 12

What is milky white and most commonly is articular cartilage at the end of long bones?

Answer 12

Hyaline cartilage

Question 13

What are cartilage cells?

Answer 13

Chondrocytes

Question 14

The axial and appendicular skeleton are??

Answer 14

The two main parts of the skeleton

Question 15

What are 3 types of cartilage?

Answer 15

1. Fibrous
2. Elastic
3. Hyaline
