Chapter 6 Skeletal System: Bones and Bone Tissue Part 1

Question 1

What are the functions of the Skeletal System ?

Answer 1

Support, Protection, Movement, Storage, and Blood Cell Production

Question 2

Components of the Skeletal System

Answer 2

bone, cartilage, tendons and ligaments

Question 3

What are the 3 types of Cartilage ?

Answer 3

hyaline, fibrocartilage, elastic

Question 4

Chondroblasts

Answer 4

specialized (immature) cells that form the matrix

Question 5

Chondrocytes

Answer 5

specialized (matured) cells that are surrounded by matrix; are in lacunae

Question 6

Matrix

Answer 6

collagen fibers for strength, proteoglycans for resiliency

Question 7

Perichondrium

Answer 7

double layered C.T. sheath; covers cartilage EXCEPT at articulations

Inner: more delicate, fewer fibers, contains chondroblasts

Outer: blood vessels and nerves penetrate. No blood vessels in cartilage itself.

Question 8

Articular cartilage (articulations)

Answer 8

covers bones at joints; has no perichondrium

Question 9

Appositional growth

Answer 9

new chondrocytes and new matrix at the periphery

Question 10

Interstitial Growth

Answer 10

chondrocytes within the tissue divide and add more matrix between the cells
