Question

match the components of the epiphyseal plate with the correct description.

1. this is the area nearest to the epiphysis that contains randomly arranged chondrocytes. (click to select)
2. this is the area where chondrocytes produce new cartilage, divide, and form columns resembling stacks of coins. (click to select)
3. this is the area where chondrocytes mature and enlarge. (click to select)
4. this is the very thin zone that contains hypertrophied chondrocytes and calcified cartilage matrix. (click to select)
5. this is the area where calcified cartilage is replaced by bone. (click to select)

Explanation:

The epiphyseal plate has different zones with distinct characteristics of chondrocytes. The zone of resting cartilage is nearest the epiphysis with randomly - arranged chondrocytes. The zone of proliferation is where chondrocytes produce new cartilage, divide and form columns. The zone of maturation and hypertrophy is where chondrocytes mature and enlarge. The zone of calcified matrix is the thin zone with hypertrophied chondrocytes and calcified cartilage matrix. The zone of ossification is where calcified cartilage is replaced by bone.

Answer:

1. Zone of resting cartilage
2. Zone of proliferation
3. Zone of maturation and hypertrophy
4. Zone of calcified matrix
5. Zone of ossification
