Cartilage

Question 1

What is cartilage (the tissue) and what cells are found within? What do the cells do?

Answer 1

connective tissue
- weaker than bone but flexible
Cells: chondroblasts and chondrocytes
Chondroblast: blast/produce matrix
Chondrocytes: mature chondroblasts surrounded by matrix (are in lacunae)

Question 2

What are the functions of cartilage? Exp of how carilage is found in respiratory system?

Answer 2

support soft tissues
- in trachea which keeps it stable
- gliding at articulations (where bones meet)

Question 3

What are the two types of growth patterns in cartilage?

Answer 3

Interstitial growth and appositional growth

Question 4

In cartilage growth, what is interstitial growth?
Where is the “new” carilage formed?

Answer 4

Interstitial growth is basically the growing of the matrix. How does this happen? When 2 chondroblasts become a chondrocyte within a lacunae. They work together to make more matrix which is a larger piece of carilage
The new cartilage is on the inside

Question 5

What is appositional growth in cartilage growth? What are the terms associated?

Answer 5

So this is just like interstitial growth but instead of new cartilage inside, new cartilage is formed outside. So the adding of chondroblasts to periphery (outside)
Terms;
Perichondreim (peri- around, chondrium- carilage)
