Question

Ilium, ischium and pubis together form……….. in rabbit.

Answer 1

Hint: They are a ring-like bony structure, located in the lower part of the trunk. They connect the axial skeleton to the lower limbs of the body. These are competent for jumping, standing, etc.

Complete answer:
The pelvic girdle of rabbits comprises ilium, ischium, and pubis. The pelvic girdle is also made up of two equal halves, both the halves are joined together mid-ventrally by pubic symphysis to make a stout and powerful girdle situated within the pelvic region between the two hindlimbs. Each half is made of three bones, the ilium, ischium, and pubis. All these bones are fused together to make one hip bone.

Additional information:
The ilium is the antero-dorsal longest bone, which bears a rough flat articular surface roughly at about the center of its length for the sacrum. The anterior and dorsal fringe of the ilium is raised into an iliac-crest. The ilium extends posteriorly up to the acetabulum. The posterodorsal part of the os-innominate is made by the ischium. The pubis does not participate directly in the formation of the acetabulum, because a cotyloid bone is situated in between the acetabulum and pubis.
Few points on Pelvic girdle are-
-The pelvic girdle is made up of two bones which are the sacrum and the coccyx.
-The pelvic girdle is made up of dual hip bones each made up of ilium, ischium, and pubis.
-The pelvic girdle is allocated in the lower area of the trunk.
-It is a ring-like bony structure.

So, the correct answer is that Ilium, ischium, and pubis together forms Pelvic girdle in rabbits.

Note:
The strong and rigid pelvis is adapted to serve a number of roles in the human body. The main functions being are-
-Transfer of weight from the upper axial skeleton to the lower appendicular part of the skeleton, mostly in the course of the movement.
-Gives attachment for a number of muscles and ligaments utilized in locomotion.
-Comprise and preserve the abdominopelvic and pelvic viscera.
