The term "pelvis triradiata" refers to the three-parted bony structure of the human pelvis. It is pronounced /ˈpɛlvɪs traɪˌreɪdiˈeɪtə/. The first part, "pelvis," is pronounced as "PELL-vis" and refers to the large bony ring that supports the spinal column and forms the socket for the hip joint. The second part, "tri," is pronounced as "TRY" and means three, while "radiata," pronounced as "ray-dee-AY-tə," means branched or radiating. Together, the term describes the pelvis' shape and structure by highlighting its three distinct branches.
The term "pelvis triradiata" refers to a specific anatomical feature found in the pelvic region of human beings. It is a term derived from Latin roots, where "pelvis" means basin and "triradiata" translates to "three radiating." The pelvis triradiata is characterized by a triangular shape formed by three main bony landmarks known as the sacral promontory, and the left and right iliopubic eminences. These landmarks serve as important reference points for assessing pelvic alignment, measuring pelvic dimensions, and understanding the relationship between the pelvis and adjacent structures.
The pelvis triradiata is a crucial aspect of pelvimetry, a branch of medicine concerned with evaluating the shape and dimension of the pelvis. Obstetricians rely on this concept to determine if a woman's pelvis has adequate space for childbirth. In obstetrics, a pelvis with a well-defined triradiate configuration is often associated with a favorable outcome for a vaginal delivery.
Furthermore, the pelvis triradiata is pivotal in anthropological studies, as often the presence of a distinct triradiate pelvis is associated with the development of bipedalism in human evolution. It is believed that the triangular shape of the pelvis helps provide stability during upright locomotion.
In summary, "pelvis triradiata" refers to the triangular arrangement formed by the sacral promontory and the left and right iliopubic eminences in the pelvic region of humans. It plays a significant role in obstetrics and anthropological research, aiding in the assessment of pelvic dimensions and childbirth feasibility.

The term "pelvis triradiata" does not have a specific etymology since it is a combination of Latin words that describe a specific anatomical feature. Here is a breakdown of its components:
- Pelvis: This word comes from the Latin word "pelvis", which means basin. It refers to the bony structure located at the base of the spine that forms the lower part of the abdomen.
- Triradiata: This word combines the Latin prefix "tri-" meaning three, and the Latin word "radiata" meaning radiating or spokes of a wheel. In this context, "triradiata" describes the three main components or branches of the pelvic bones, which include the ilium, ischium, and pubis.
Combining these two elements, "pelvis triradiata" refers to the three main bones that make up the pelvis.
