Elastic Cartilage · Histology

During the development of elastic cartilage, which cells are responsible for secreting the elastic fibers?

  1. Fibroblasts in the outer perichondrium
  2. Osteoblasts migrating from the surrounding periosteum
  3. Macrophages clearing the matrix
  4. Young chondroblasts and mature chondrocytes
Show answer and explanation

Correct answer: Young chondroblasts and mature chondrocytes

Both chondroblasts and chondrocytes within the developing elastic cartilage synthesize and secrete the components of both the collagenous and elastic fibers into the extracellular space.
