lantioissa

Lantioissa is an inessive plural form of the Finnish noun lantio, meaning pelvis. It is used to indicate location inside the pelvic region when reference involves more than one pelvis. In Finnish grammar, the inessive case expresses “in” and the plural suffix -issa/-issä marks plurality; thus lantioissa literally translates to “in the pelvises” or, in broader contexts, “in the pelvic region” when referring to multiple individuals or specimens.

The pelvis (lantio) is the basin-shaped structure at the base of the spine that forms the pelvic girdle with the two hip bones. Each hip bone consists of the ilium, ischium, and pubis, which fuse in adulthood. The pelvic cavity contains pelvic organs such as the bladder and reproductive organs and is separated from the abdominal cavity by the pelvic brim. The pelvic floor muscles support pelvic organs and help control continence and core stability.

Lantioissa appears mainly in technical or academic Finnish. In everyday language, referring to a single pelvis, lantiossa is used. The form is common in anatomical descriptions, medical texts, and comparative studies across individuals or species.
