The correct spelling of the anatomical term "true pelvis" is /truː ˈpɛlvɪs/. The word "true" is pronounced with a long 'u' sound followed by a soft 'r'. The 'e' in "pelvis" is pronounced like short 'e' sound. The true pelvis is the lower part of the pelvis, consisting of the pelvic brim and floor. It is important to use the correct spelling and pronunciation of medical terms to avoid confusion and ensure accurate communication among healthcare professionals.
The true pelvis, also known as the lesser pelvis or the pelvic cavity, is a fundamental anatomical structure found in the human body. It is a ring-like structure located at the base of the trunk, between the sacrum and coccyx posteriorly and the pubic symphysis anteriorly. This bony structure forms the lower portion of the pelvic girdle and serves as a protective enclosure for vital organs and structures of the urogenital and digestive systems.
The true pelvis is divided into two distinct regions, the pelvic inlet and the pelvic outlet. The pelvic inlet is the upper opening of the true pelvis, defined by the sacral promontory posteriorly and the pubic symphysis anteriorly. It establishes the boundary between the abdominal and pelvic cavities. The pelvic outlet, on the other hand, is the inferior opening of the true pelvis, characterized by the coccyx posteriorly, the ischial tuberosities laterally, and the pubic arch anteriorly. This region serves as a passage for childbirth, as well as for the elimination of waste material.
Alongside its protective function, the true pelvis plays a crucial role in supporting and stabilizing the weight of the upper body. Additionally, it provides attachment points for various muscles, ligaments, and connective tissues of the pelvic floor. The true pelvis is of significant importance in obstetrics and gynecology, as it directly affects pregnancy and childbirth by accommodating the growing fetus and guiding its passage through the birth canal. Understanding the anatomy and dimensions of the true pelvis is essential in these medical fields to ensure optimal maternal and fetal health during pregnancy and delivery.

The word "true" in "true pelvis" is derived from the Latin word "trūs", meaning "genuine" or "real". The term "true pelvis" refers to the lower portion of the pelvis, which is the bony structure located between the hips. It includes the bony ring formed by the sacrum, coccyx, and ischium. The term emphasizes that this part of the pelvis is the authentic or genuine pelvis, as opposed to the "false pelvis" (also known as the greater pelvis) located above it.
