The opening of the urethra is the external urethral orifice.
The median sacral crest on the sacrum is a bony ridge formed by fusion of sacral vertebrae, indicating where the individual vertebrae once were. In contrast, the median sacral crest on lumbar vertebrae does not exist, as lumbar vertebrae do not fuse in the same way as sacral vertebrae.

The sacral median crest is a bony ridge located on the posterior surface of the sacrum, formed by the fusion of the spinous processes of the sacral vertebrae. Its primary function is to provide attachment points for ligaments and muscles, contributing to the stability and support of the pelvis. Additionally, it serves as a landmark for the sacral canal, which houses the sacral spinal nerves. Overall, the sacral median crest plays a crucial role in the structural integrity of the sacral region.
