Explanation
Microcephaly is a neurological condition in which a baby's head is much smaller than expected for the baby's age. The head circumference is typically below the third percentile for the baby's sex and age. Microcephaly can be caused by a variety of genetic and environmental factors, and it can be associated with a range of developmental disabilities.

About Growth and Development
Embryonic development covers fertilization, cleavage, formation of the blastula and gastrula, germ layers, organ formation and differentiation. Regeneration describes the replacement of lost tissues or body parts, whereas ageing involves gradual cellular and physiological changes linked to reduced repair, altered metabolism and declining organ function.
