Question

What would be the physical sign that a bone cannot continue longitudinal growth?

Answer 1

Answer:

c) The presence of an ephiphyseal line

Explanation:

The options should be:

a) the presence of osteoblasts

b) the presence of osteons

c) The presence of an ephiphyseal line

d) the presence of hyaline cartilage on the ends of the bone

Explanation:

In vertebrates, the epiphyseal line is formed once the bone is completely grown. This occurs inside a plate known as the epiphyseal plate.

From the age of 18 to 21, the bone stops growing and the cartilage inside this plate gets replaced by bone. However, bones can keep growing in width until we are approximately 25 years old.

Therefore, the physical sign that indicates that a bone cannot continue longitudinal growth would be the presence of an ephiphyseal line.
