Question 1

State what type of cartilage provides structure, where it is found and what is required functionally.

Answer 1

• Hyaline cartilage found in nose & embryonic skeleton, for relative rigidity.
• Elastic cartilage found in external ear, for flexibility.
• Fibrous cartilage found in invertebral discs, for rigidity

Question 2

State what kind of cartilage provides support, where it is found and what is required functionally.

Answer 2

• Hyaline cartilage found in tracheal rings, for maintenance of airways

Question 3

State what kind of cartilage provides growth, where it is found and what is required functionally.

Answer 3

Hyaline cartilage found in the embryonic skeleton and epiphyseal growth plates, for rapid growth

Question 4

State what kind of cartilage provides flexibility, where it is found and what is required functionally.

Answer 4

Elastic cartilage found in the epiglottis and external ear, for firmness with flexibility

Question 5

State what kind of cartilage serves as a model, where it is found and what is required functionally.

Answer 5

Hyaline cartilage found in long bone ossification for development of body shape before bone development

Question 6

State what kind of cartilage is in joints, where it is found and what is required functionally.

Answer 6
