Question

Describe briefly about pelvic girdle.​

Answer 1

Answer:

The pelvic girdle is a ring-like bony structure, located in the lower part of the trunk. It connects the axial skeleton to the lower limbs.

In this article, we shall look at the anatomy of the pelvic girdle – its bony landmarks, functions, and its clinical relevance.

Structure of the Pelvic Girdle

The bony pelvis consists of the two hip bones (also known as innominate or pelvic bones), the sacrum and the coccyx.

There are four articulations within the pelvis:

Sacroiliac joints – between the ilium of the hip bones, and the sacrum

Sacrococcygeal symphysis – between the sacrum and the coccyx.

Pubic symphysis – between the pubis bodies of the two hip bones.

Ligaments attach the lateral border of the sacrum to various bony landmarks on the bony pelvis to aid stability.

Functions of the Pelvis

The strong and rigid pelvis is adapted to serve a number of roles in the human body. The main functions being:

Transfer of weight from the upper axial skeleton to the lower appendicular components of the skeleton, especially during movement.

Provides attachment for a number of muscles and ligaments used in locomotion.

Contains and protects the abdominopelvic and pelvic viscera.
