Regarding cartilage growth, which of the following is the EXCEPTION (false statement)?

  1. Cartilage grows in length by interstitial growth
  2. Cartilage grows in length by appositional growth
  3. Cartilage growth occurs by intramembranous ossification
  4. Cartilage resists direct compression better than bone
Show answer and explanation

Correct answer: C. Cartilage growth occurs by intramembranous ossification

  • A. ❌ Cartilage DOES grow by interstitial growth (chondrocytes divide within the matrix) — TRUE.
  • B. ❌ Cartilage DOES grow by appositional growth (new cells added at the perichondrium) — TRUE.
  • C. ✅ Correct (exception). Cartilage does NOT grow by intramembranous ossification. Intramembranous ossification forms flat bones (skull). Cartilage grows by appositional/interstitial growth or is replaced by bone via ENDOCHONDRAL ossification.
  • D. ❌ Cartilage IS better at resisting direct compression than bone — TRUE.
