Question

Total number of bones in appendicular skeleton of rabbit is
(A) 128
(B) 120
(C) 80
(D) 37

Answer 1

Hint: Bones are the dense connective tissue that provide the structural support to the body and it helps in maintaining the correct position of all the organs in the body. This constitutes the part of the organ in the vertebrates. The bones store minerals in them like calcium etc. They help in the production of the red and the white blood cells.

Complete answer:
The skeletons in the mammals are classified into two types as the axial skeleton and the appendicular skeletons. The axial skeleton is the skeleton that is present in the longitudinal axis of the body. The skull, ribs, sternum and the vertebral column are the example for the axial bones. In the rabbit, there are about 132 axial bones in it.
The appendicular skeleton forms the rest of the skeleton and they form appendages to the axial skeleton. It includes the bones in the pectoral or the shoulder girdle, pelvic girdle, upper limbs and the lower limbs of the body. In rabbits there are about 128 appendicular bones and in humans there are 126 appendicular bones.

Hence the correct answer is option(A)

Note: The pectoral girdle joins up the upper limbs of the body. The pelvic girdle helps in bearing the weight of the whole body and it is also responsible for the locomotion. The pelvic girdle also serves as the attachment of the lower limbs to the body. The lower limbs are used for locomotion and it supports the whole weight of the body.
