Multiple Choice

As a person ages, what happens to the growth plate that can be used as an indicator of age?

It dissolves completely, leaving a hollow space

It develops more blood vessels and expands

It ossifies and becomes a solid bone structure

It increases in thickness and remains cartilaginous

Verified step by step guidance

Understand the role of the growth plate (also known as the epiphyseal plate) in bone development. It is a layer of cartilage found in growing bones, responsible for longitudinal growth during childhood and adolescence.

Recognize that as a person ages and reaches skeletal maturity, the growth plate undergoes a process called ossification. Ossification is the transformation of cartilage into bone tissue.

Learn that during ossification, the cartilage cells in the growth plate are replaced by bone cells, resulting in the growth plate becoming a solid bone structure. This process marks the end of bone growth in length.

Understand that the ossification of the growth plate can be used as an indicator of age because it typically occurs at specific stages of development, depending on the individual and the bone in question.

Note that the other options provided in the problem are incorrect because the growth plate does not dissolve completely, develop more blood vessels and expand, or increase in thickness while remaining cartilaginous. Instead, it ossifies and becomes a solid bone structure.
