Pelvis

The pelvis is a bony structure that forms the lower part of the trunk and supports the abdominal and pelvic organs. It is made up of four bones: the two hip bones (ilia), the sacrum, and the coccyx. The hip bones are the large, fan-shaped bones that form the sides and front of the pelvis. The sacrum is a triangular bone that forms the back of the pelvis. The coccyx is a small, triangular bone that forms the tip of the pelvis.

Functions of the Pelvis

The pelvis has several important functions. It provides support for the abdominal and pelvic organs, protects them from injury, and allows for the passage of blood vessels, nerves, and lymphatic vessels. The pelvis also plays a role in childbirth, providing a passageway for the baby to pass through during delivery.

Anatomy of the Pelvis

The pelvis is divided into two parts: the true pelvis and the false pelvis. The true pelvis is the smaller, lower part of the pelvis that contains the pelvic organs. The false pelvis is the larger, upper part of the pelvis that is located above the true pelvis. The true pelvis is bounded by the pubic bones, the ischia, and the sacrum. The false pelvis is bounded by the ilia, the sacrum, and the coccyx.

Clinical Significance of the Pelvis

The pelvis is a clinically important region of the body. It is often the site of pain and discomfort, and it can be affected by a variety of injuries and diseases. Some of the most common conditions that affect the pelvis include:

• Pelvic pain
• Pelvic injuries
• Pelvic inflammatory disease
• Pelvic organ prolapse
• Pelvic cancer
