Question

Two halves of pelvic girdle are joined together by:
A. Pubic symphysis
B. Ischiac symphysis
C. Ischibpubic symphysis
D. By fusion

Answer 1

Hint: Pelvic girdle is located in the lower part of the trunk. Each canal bone is formed by the fusion of three bones. Pelvic girdle is also called hip girdle, is formed by two bones i.e. coxal bones.

Complete answer
Pelvic girdle is formed by two coxal bones.
Two halves of pelvic girdle are joined together by pubic symphysis. It contains fibrous cartilage.
Each coxal bone is formed by fusion of three bones- Ilium, ischium and pubis. At the point of fusion of the above bones is a cavity called acetabulum to which the thigh bone articulates.
Below the acetabulum, the innominate has a large oval gap, the obturator foramen.
The pelvic girdle serves several important functions in the body. It supports the weight of the body from the vertebral column. It also protects and supports the lower organs, including the urinary bladder and the reproductive organs.

Hence the correct option is A. Pubic symphysis.

Note:The female pelvis is large and has a broader front and larger bottom opening than the male pelvis. This is an adaptation for childbirth.
