Vestigial Organs

My ugly little toe is considered a vestigial organ because it's not a necassary organ needed for me to continue on living my life.

Vestigial organs, also known as rudimentary organs are structures that seem to have served a purpose in the past, but now when closely looked at seem to serve little to no purpose. Another factor for these structures being considered rudimentary is that they have lost their past abilities to function properly. Some structures that are considered to be vestigial organs would be your wisdom teeth, tonsils and even the nipples on a man.
