The Perineum
We consider the perineum within the bony structure although it is not a bone. We include it because it is not on the outside of the body and does not suffer location alterations due to adipose tissues.
The perineum is the space between the anus and the external genitalia.
It marks the beginning of the legs of the lower garments and the end of the trunk.
It divides the lower garments into two different parts: the trunk part and the leg part gf the garment.
