Questions and Answers
What is the main reason that elastic cartilage appears more opaque and yellow than hyaline cartilage?
Which of the following is a characteristic of elastic cartilage that sets it apart from other cartilage types?
Which of the following structures contain elastic cartilage?
Study Notes
- Elastic cartilage is more opaque and yellow than hyaline cartilage due to abundant elastic fibers.
- It is resilient and has more flexibility and elasticity than other cartilage types.
- The matrix contains a dense network of elastic fibers and a small amount of ground substance.
- Chondrocytes in elastic cartilage are closely packed and often found singly in lacunae.
- Type I collagen fibers are present but masked by ground substance and intermingle with elastic fibers.
- Elastic cartilage is enveloped by a perichondrium and does not have blood vessels or lymphatics in the cartilage interior.
- It undergoes appositional growth from the perichondrium or interstitial growth by chondrocyte mitosis.
- Elastic cartilage does not calcify with age.
- Elastic cartilage is found in the external ear, epiglottis, and larynx.
- Elastic cartilage is important for maintaining shape and function in these structures.
