ABSTRACT
A newborn infant more than triples in height and increases in
weight some 20-fold before reaching maturity. During the
process, structures change in size and position. Some, which
are critically important during fetal development, disappear.
Most persist but grow at different rates and at different ages.
It is therefore not surprising that newborn anatomy differs
from adults; some of these differences are particularly
important for the pediatric surgeon (Table 3.1 and Fig. 3.1).
This chapter summarizes the applied anatomy of the new-
born, emphasizing aspects that are clinically relevant and
different to adults.
