Questions and Answers

What is the function of the epiphyseal plate in long bone growth?

  • It allows bone growth up to adult length/full maturation (correct)
  • It facilitates the formation of the bone marrow cavity
  • It prevents further bone growth after reaching adult length
  • It acts as a barrier to separate the diaphysis from the epiphysis
  • Which process leads to the formation of the bone collar?

  • Intracartilaginous ossification
  • Intramembranous ossification within the periosteum (correct)
  • Calcification of the epiphyseal plate
  • Endochondral ossification
  • What is the role of the primary ossification centre (diaphysis) during bone development?

  • It allows for diametric growth of the bone
  • It results in the replacement of cartilage by bone in the middle of the shaft (correct)
  • It facilitates the formation of the bone marrow cavity
  • It initiates bone formation at the ends of the cartilage
  • What is the purpose of the secondary ossification centre (epiphysis)?
