cartilage

Question 1

What is perichondrium

Answer 1

Surrounds the cartilage

Dense irregular connective tissue that contains blood vessels

Question 2

What are the 3 types of cartilage

Answer 2

Hyaline
Elastic
Fibrocartilage

Question 3

What is a chondrocyte

Answer 3

Cells responsible for cartilage formation

Question 4

Describe hyaline cartilage and its function

Answer 4

Slippery and smooth which helps your bones move smoothly past each other in your joints

Flexible but strong enough to hold joints in place

Question 5

Name the locations of hyaline cartilage

Answer 5

Joint cavities
Cartilage of nose, trachea and larynx

Question 6

Describe elastic cartilage and its function

Answer 6

Like hyaline but more flexible

Can bounce to its original shape after strong force

Question 7

Name the location of elastic cartilage in the body

Answer 7

External ear and epiglottis

Question 8

Describe fibrocartilage and its function

Answer 8

Fibrocartilage is very strong

Main function is to act as a cushion to the joints, helps manage compressive forces

Question 9

Name the location of fibrocartilage

Answer 9

Intervertebral discs
Pubic symphysis
Discs of knee joint (menisci)

Question 10

What types of cartilage growth can occur

Answer 10

Appositional and interstitial

Question 11

Mitosis

Answer 11

A process where a single cell divides into two identical daughter cells

Question 12

Appositional growth

Answer 12

Cartilage cells grow from the perichondrium

Question 13

Interstitial growth

Answer 13

Cartilage cells grow from the chondrocytes within the cartilage

Question 14

Lacunae

Answer 14

A cavity or depression, especially in bone

Question 15

Chrondroblast

Answer 15

Mesenchymal progenitor cells that actively produce the components of the extracellular matrix of cartilage

Question 16

Extracellular matrix

Answer 16

3-D network of macromolecules that provides support for the cells and tissues.

Question 17

Describe the cartilage based on these points:

1) Perichondrium
2) Blood vessels and nerves
3) What is in the lacunae
4) Properties of Extracellular matrix, what are they made by
5) Types of growth

Answer 17

1) Surrounded by perichondrium
2) No blood vessels or nerves
3) Chondrocytes in lacunae
4) Flexible extracellular matric and made by the chondroblasts
5) Appositional and interstitial

Question 18

What are the 7 functions of bones

Answer 18

Fat storage
Mineral storage
Support
Blood cell formation
Anchorage
Protection
Hormone production

Question 19

What minerals are stored in the bones

Answer 19

Calcium and Phosphorus

Question 20

Where does fat storage take place in the bones

Answer 20

Yellow bone marrow

Question 21

Hormone production in the bones

Answer 21

Osteocalcin

Question 22

What does osteocalcin do?

Answer 22

Helps to regulate insulin secretion, glucose homeostasis and energy expenditure
