Cellular Growth Disorders
Definition of growth
Factors controlling cellular growth and differentiation
Characters of physiological growth
Abnormalities of cellular growth that are either
Excesses (hypertrophy and hyperplasia) or
Decreases which are either
Developmental (agenesis, aplasia and hypoplasia)
Acquired after full development (atrophy)
Abnormalities of cellular differentiation
It comprise metaplasia and dysplasia
