2. Costal cartilages

3. Laryngeal cartilages

4. Tracheal and bronchial cartilages

5. Nasal cartilages

6. Intervertebral disc cartilages

7. Cartilage in the external ear

3

The articular cartilages cover what?

Bone ends at moveable joints

4

The costal cartilages connect what to what?

They connect the ribs to the sternum.

5

The laryngeal cartilages construct what?

larynx

6

The tracheal and bronchial cartilages reinforce what of the which body system?

They reinforce other passageways of the respiratory system.

7

The nasal cartilages support what body feature?

Support the external nose

8

Function of the intervertebral disc cartilages?

Separate and cushion vertebrae bones.

9

The external ear cartilage provides what to the external ear?

Support the external ear.

10

Cartilage tissues are distinguished by what 2 particular features?

2. Have very few blood vessels

11

Each cartilage is specifically surrounded by what?

perichondrium

12

The perichondrium is composed of what type of tissue?

dense irregular connective tissue

13

The perichondrium resist what and allow cartilage to do what 2 things?
