In bone repair, which occurs first?Multiple choice question.Callus formationHematoma formationCallus ossification

Break Down the Problem

1. Identify the sequence of events in the bone repair process.
2. Analyze each option to determine the correct order.

Relevant Concepts

• Bone repair generally follows a sequence:
  • Hematoma formation
  • Callus formation
  • Callus ossification

Analysis and Detail

1. Hematoma Formation: This is the initial response to a fracture where blood starts to clot around the broken area, forming a hematoma.
2. Callus Formation: After hematoma formation, a soft callus begins to develop as cells start to migrate to the injured site to form cartilage.
3. Callus Ossification: Finally, the soft callus is replaced by a hard callus through the process of ossification where new bone is formed.

Verify and Summarize

• The questions ask for the first occurrence in bone repair. Based on the sequence of events, hematoma formation is the first step in the repair process.

Final Answer

Hematoma formation occurs first in the process of bone repair.
