CHAPTER 5 III The Wing: Normal Gross Anatomy 63

Figure 5-10 • Close-up view of the
lateral aspect of the distal ulna in a
Canadian goose (prepared specimen).
Note the distinctive shape of the ulnar
epiphysis and its spatial relationship to
the adjacent, fl exed carpometacarpus.

Figure 5-11 • A great
horned owl (recently
deceased) with its
feathers and most of its
fl esh removed from the
proximal half of the wing,
revealing the shoulder,
humerus, elbow, radius,
and ulna. It then becomes
apparent that the interior
support for better than
50% of the wing is
composed of its smallest
bones: the carpus,
metacarpus, and digits.

III CARPUS, METACARPUS, wing—the carpus, metacarpus, and digits—support
AND DIGITS and control the largest of the flight feathers, which

constitute more than half the total length of the wing
Although their true functional importance often goes (Figure 5-11). The bones of the distal wing are shown
unrecognized, the distal skeletal elements of the in Figure 5-12.
