Pelvic girdle

Pelvic Girdle

The Pelvic Girdle (pronunciation: /ˈpɛlvɪk ˈɡɜːrdl/) is a complex, basin-shaped structure that connects the spine to the lower limbs. It is composed of two hip bones, the sacrum, and the coccyx.

Etymology

The term "pelvic" originates from the Latin word "pelvis," which means "basin." The term "girdle" comes from the Old English word "gyrdel," which means "belt." Thus, the term "pelvic girdle" can be interpreted as a "basin belt."

Structure

The pelvic girdle is made up of two hip bones, each of which is formed by the fusion of three bones: the ilium, the ischium, and the pubis. These bones are connected at the pubic symphysis, a cartilaginous joint. At the back, the hip bones connect to the sacrum at the sacroiliac joints. The coccyx, or tailbone, is located at the base of the sacrum.

Function

The primary function of the pelvic girdle is to support the weight of the upper body and transfer it to the lower limbs. It also provides attachment points for numerous muscles, including those of the abdomen, back, and buttocks. The pelvic girdle also protects the internal pelvic organs, such as the bladder, rectum, and in women, the uterus and ovaries.
