Analyze Question 26

The question asks: "What tissue serves as the model for bones formed during endochondral ossification?"

• Endochondral ossification is the process of bone development from a pre-existing model.
• During embryonic development, this precursor model is composed of hyaline cartilage.
• Gradually, this cartilage model is replaced by bone tissue.
• Therefore, hyaline cartilage is the correct tissue model.

Analyze Question 27

The question asks: "The patella is classified as a sesamoid bone since it:"

• We apply the concept of Bone Classification to identify the unique characteristics of sesamoid bones.
• Sesamoid bones are small, rounded bones that develop inside tendons where there is considerable pressure, friction, and physical stress (such as the knee joint).
• The patella (kneecap) is the largest sesamoid bone in the body and is located within the quadriceps femoris tendon.
• Therefore, the correct option is that it is located within tendons.
