Scammon’s Growth Curve
The body tissues can be broadly classified into four types, i.e. lymphoid tissue, neural tissue, general tissue and genital tissue. Each of these tissues grows at different times and at different rates.
- Lymphoid tissue proliferates rapidly in late childhood and reaches almost 200% of adult size. This is an adaptation to protect children from infection as they are more prone to it. By about 18 years of age, lymphoid tissue undergoes involution to reach adult size.
