Morphology

lumbosacral = lumbar + sacral (transparent) = lumbo + sacral

Composition of 'lumbar' and 'sacral' indicating the region where lumbar spine meets sacrum; clear anatomical compound.

Etymology

Lumbosacral comes from two parts: lumbo- meaning 'loin' or 'lower back', which you see in lumbar, and sacral from sacrum, the bone at the base of the spine that was once called 'sacred'. So, lumbosacral describes the area where the lower back meets that base bone.
