The Arm The Arm (Plate 63).
In very young children the muscles of the arm are covered with rolls of fat, giving it a thick appearance. Fig. 1 shows the arm of a child of three years of age.
As a boy develops, his muscles become more defined in
the arm, the wrist broadens and hands become square in form. (See Fig. 2, the arm of a boy at fourteen years of age.)
The muscles of a girl's arm are softer in outline, tapering to wrist, hands long and thin. Fig. 3 gives the outline of the arm at fourteen years of age.
Both sexes, between fifteen, sixteen, and seventeen, conform with adult formation of outline in their right proportion of growth.
