Question

The pelvic girdle of a rabbit consist of:
A. Illium, ischium, pubis
B. Illium, ischium, coracles
C. Coracoid, scapula, clavicle
D. Illium, coracles, scapula

Answer 1

Hint: The ecosystem is the structural and functional unit of ecology where living (biotic component) and non-living (abiotic component) interact with each other. It is the study of inter-relationships among the living organisms, biochemical, natural phenomena, and all the human activities in ecological communities.

Complete answer:.
> The ischium forms the hip bone, lower and back part. The ilium is the largest of the three innominate bones of the pelvis. It is a large, flattened, somewhat cup-shaped bone having a large crest anteriorly. The pubic symphysis is a midline or secondary cartilaginous joint located between the left and right pubic bones of the median plane. So the correct option is A.
> Coracles definition: designating or of a rudimentary bony process on the shoulder blade in mammals. So option B is incorrect.
> The clavicle is the bone present in the shoulder and breast bone. So the option C is incorrect.
> The pelvic girdle comprises the usual three bones ilium, ischium, and pubis which are fused into a single innominate or hip bone. So the option D is incorrect.

Hence the option A is correct.

Note: The pelvic girdle is made up of the ilium, ischium, and pubis. Scapula and the other bones do not make up the pelvic girdle of the rabbit. The rabbit consists of the ilium ischium and pubis bones. A pelvic girdle is a cartilage present that helps to support the hind limbs.
