The document summarizes the appendicular skeleton of chickens. It describes that the wing consists of the upper arm (humerus) and lower arm (radius and ulna). It also details the bones in the forearm, wrist, hand, and thumb wing. For the lower limb, it outlines that chickens have a femur, fibula, and tibia like humans, and identifies the major leg joints and bones, including that chickens walk on their toes in a digitigrade manner.

Skeleton of the
Chicken

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.
