kõhupealse
Kõhupealse is an Estonian term that translates to "belly button" or "navel." It refers to the scar that remains on the abdomen after the umbilical cord is severed at birth. This small indentation or protrusion is a universal feature in humans and many other mammals. The appearance of the kõhupealse can vary from person to person, being either an "innie" (an indentation) or an "outie" (a protrusion). The exact reason for these variations is largely genetic and related to how the umbilical cord heals.
The kõhupealse plays no functional role after birth but serves as a visible reminder of fetal development.
