SURFACE ANATOMY OF THE NEWBORN The surface anatomy of a newborn infant represents an early stage of human development; therefore, it differs from that of an adult. Certain aspects of the surface anatomy of a neonate are of clinical importance in ascertaining the degree of physical develop- ment, general health, and possible congenital abnormalities.
