Differentiate between the three different types of ages in terms of growth and development.

Question 1

Chronological Age

Answer 1

Age measured in years, months, and days; this is, the standard set of the term “age”.

Question 2

Skeletal age

Answer 2

• Skeletal age is measured by how bones grow and harden.
• X-rays of the hand and wrist are used to check this.
• Skeletal age might not match a person’s actual age.
• Differences can be caused by:
  1. Diet
  2. Illness
  3. Injuries
• Knowing skeletal age helps us understand how the body develops.

Question 3

Developmental age

Answer 3

• Developmental age looks at physical, mental, social, and emotional growth.
• It shows how well someone can do certain tasks.
• Example: “He’s seven but serves like a teenager” compares actual age to developmental age.
• This highlights the difference between chronological age and developmental age.
