Neonatal growth and anatomy refer to the development and structure of a newborn baby. During the neonatal period, which typically spans the first 28 days of life, rapid growth and significant anatomical changes occur. This period is characterized by the maturation of various organs and systems, including the respiratory, circulatory, digestive, and nervous systems. Understanding neonatal growth and anatomy is crucial for ensuring proper care and monitoring of newborns to promote healthy development and early detection of any abnormalities.
