'''Linea Terminalis'''

The '''Linea Terminalis''' is a term used in [[anatomy]] to describe a curved ridge on the internal surface of the [[pelvis]]. It is also known as the terminal line, and it marks the boundary between the true and false pelvis.

==Etymology==
The term "Linea Terminalis" is derived from Latin, where "Linea" means line and "Terminalis" means terminal or end. Thus, it can be translated as the "end line" or "terminal line".

==Anatomy==
The Linea Terminalis is a curved ridge that separates the [[pelvis]] into two parts: the true pelvis and the false pelvis. The true pelvis is the lower part, which is bounded by the [[pelvic inlet]] and the [[pelvic outlet]]. The false pelvis is the upper part, which is above the Linea Terminalis and is part of the [[abdominal cavity]].

The Linea Terminalis is formed by the [[pectineal line]] of the [[pubis]], the [[arcuate line]] of the [[ilium]], and the [[sacral promontory]]. These three structures form a continuous line that runs from the pubic bone to the sacrum.

==Clinical Significance==
The Linea Terminalis plays a crucial role in [[obstetrics]]. It is used to determine the shape and size of the [[pelvic inlet]], which can affect childbirth. A narrow or irregularly shaped pelvic inlet can cause complications during [[childbirth]], such as obstructed labor.
