Cartilage and joints

Question 1

Cartilage

Answer 1

• -flexible, resilient connective tissue
• -composed mostly of collagen
• -contains no blood vessels or nerves except in its outside membrane

Question 2

3 types of cartilage

Answer 2

1. hyaline
2. fibrocartilage
3. elastic

Question 3

Joints

Answer 3

–where bones connect

Question 4

3 types of joints

Answer 4

1. Fibrous joints
2. Cartilaginous joints
3. Synovial joints

Question 5

Fibrous joints

Answer 5

• -purpose is to maintain a fixed relationship between two bones
• -between two bones held closely and tightly by fibrous connective tissue
• -allows the least movement of any joint type
• -ex: joint between teeth and mandible, skull bones form fibrous joints w/ each other

Question 6

Cartilaginous joints

Answer 6

• -allow little movement
• -occur b/w two bones tightly connected by cartilage
• -slight flexibility can allow absorption of some energy to protect bones from trauma
• -ex: joint b/w ribs and sternum, joint b/w pubic symphysis in the pelvis

Question 7

Synovial joints

Answer 7

• -allow a wide range of movement
• -bones are not bound directly by the intervening cartilage, but instead are separated by a capsule filled with synovial fluid
• -ex: shoulder and knee joints

Question 8

synovial fluid

Answer 8

• -provides lubrication and nourishment to the cartilage in synovial joints
• -contains phagocytosis cells that can remove microbes and particles
