3. WINGS

4. There are two major sections to the arm.
 The upper arm is made up of the
humerus, while the lower arm consists
of the radius and the ulna.

5. The Humerus
 The humerus is a hollow bone with a broad
head at the proximal (body) side that forms
the shoulder.

7. The Radius and Ulna
 The ulna and radius together form the
forearm and are usually about as long as the
humerus.
 The ulna is the 'heaviest' bone of the two.

9. Ulnare and radiale
 These two small bones form the wrist and
apart from some minor differences more or
less the same built in most birds.

10. Carpometacarpus
 This is equivalent to the metacarpal bones in
mammals, but in birds these are reduced to a
single bone, with a foramen in the middle. In
fact, here are two metacarpals fused into
one, that of the 2nd and 3rd finger.

12. Alula
 The alula (thumb wing) consists of one
phalanx (occasionally two, sometimes even
with a nail in some bird species).
 It is a freely movable digit with a few small
feathers attached.

13. Lower Limb
 they both have a femur, fibula, and tibia
 The femur of a chicken holds the thigh meat
 the fibula/tibia combination holds the meat of
the drumstick.
 Comparing the leg joints is not quite as
obvious as with the arm.
 Joint at the top of the femur = hip

15.  -Joint between femur and the fibula/tibia =
knee
 -Joint between fibula/tibia = ankle
 -The metatarsus of a chicken is known as the
shank.
 -The chicken walks up on its toes.
