HUMAN GROWTH AND DEVELOPMENT

Human growth and development encompass the continuous physical, psychological, and functional changes that occur throughout the lifespan, from conception to old age. Growth represents quantitative changes in body size and structure, while development reflects qualitative changes in functional abilities, emotional maturity, and intellectual capacity. This chapter outlines the fundamental concepts of human growth and development, beginning with embryological and fetal development, followed by postnatal stages including the neonatal period, infancy, childhood, adolescence, adulthood, and aging. It also highlights the importance of growth milestones, developmental assessment, and the identification of developmental disorders. Special emphasis is placed on pediatric and geriatric pathophysiology, underscoring age-specific vulnerabilities and healthcare needs. Understanding these processes is essential for healthcare professionals to recognize normal developmental patterns, detect deviations early, and provide effective, age-appropriate care across the human lifespan.
