Cartilage

Question 1

Cells?

Answer 1

-Chondrocytes
-Chondroblasts

Question 2

Function?

Answer 2

-tough but flexible CT that provides support

Question 3

Hyaline Cartilage

Answer 3

Function: Reduce friction
Location: Synovial joints (No perichondrium)
Weakest and most common

Question 4

Elastic Cartilage

Answer 4

Function: stretch and return
Location: auricle of the outer ear, epiglottis, auditory canal

Question 5

Fibrous Cartilage

Answer 5

Function: Padding (resist compression, prevent bone-bone contact, limit movement)
Location: Menisuc, pubic symphysis, intervertebral disks

Question 6

What is perichondrium? Is it vascular?

Answer 6

Layer that separates cartilage from surrounding tissue
-vascular

Question 7

What fibers in cartilage

Answer 7

-mainly collagen, some elastic

Question 8

collagen Matrix?

Answer 8

firm gel with chondroitin sulfates

Question 9

What are the two types of cartilage growth?

Answer 9

-appositional (surface)
-interstitial (increased volume)

Question 10

Appositional cartilage growth

Answer 10

-at surface
-chondroblasts secrete in all directions, get trapped, mature into chondrocytes in lacuna

Question 11

Interstitial cartilage growth

Answer 11

-increased volume
chondrocyte undergoes division within the lacuna
-daughters secrete more matrix, move apart
