Question

Which of the following is an example of appendicular skeleton?
A) Bones of skull
B) Bones of vertebral column
C) Ribs
D)Bones of fore and hind limb

Answer 1

Hint: In man, skeleton is divided into two main parts- axial skeleton and appendicular skeleton, each having sub parts. Skeletons can absorb the tremendous shocks generated in locomotion.

Complete answer:
Axial skeleton:-
It occupies the body’s main axis of the body. It contain four parts
>Skull in the head
>Vertebral column in the neck and trunk
>Sternum
>Ribs in thorax
Appendicular skeleton:-
It is placed in the side axes. It contain
>Pectoral and pelvic girdles
>Limb bones
>The pectoral and pelvic girdles connect the limb bones with the vertebral column.

Additional information:
Each forelimbs has Humerus (Upper arm), radius and ulna (forearm), carpals (wrist bone), metacarpals and phalanges.
Each Hind Limbs has Femur (thigh bone), Tibia and fibula (shank bones), tarsals (ankle), metacarpals and phalanges.
Girdles afford the attachment to certain muscles of the arm and legs.
Limb bone helps to effective movement of arms and legs.

So, the correct answer is bones of fore and hind limb is the example of appendicular skeleton.

Note:The hard and protective elements of the body are known as skeleton systems. Basically, it is a three type hydrostatic skeleton, exoskeleton and endoskeleton. In human beings the endoskeleton system is present which is composed of bones and cartilage.
