Pelvic brim

Pelvic brim

The Pelvic brim is a significant anatomical structure in the human body, specifically in the pelvis. It is also known as the pelvic inlet, marking the boundary of the pelvic cavity.

Etymology

The term "pelvic brim" is derived from the Latin word "pelvis," which means basin, and the Old English word "brim," which means edge or border.

Anatomy

The pelvic brim is an anatomical structure that separates the greater pelvis (also known as the false pelvis) from the lesser pelvis (also known as the true pelvis). It is a line from the sacral promontory to the upper, inner edge of the pubic symphysis. It is an important landmark in the study of obstetrics as it forms the birth canal in females.

Clinical significance

The shape and size of the pelvic brim can have significant implications in childbirth. A narrow or irregularly shaped pelvic brim can lead to complications during labor and delivery. It is also used in the classification of the pelvic girdle in forensic anthropology.
