Vestigial organs

blind-ended tube connected to the cecum, from which it develops embryologically

The coccyx (: coccyges or coccyxes), commonly referred to as the tailbone, is the final segment of the vertebral column in all apes, and analogous structures in certain other mammals such as horses. In tailless primates (e.g. humans and other great apes) since Nacholapithecus (a Miocene hominoid), the coccyx is the remnant of a vestigial tail. In animals with bony tails, it is known as tailhead or dock, in bird anatomy as tailfan. It comprises three to five separate or fused coccygeal vertebrae below the sacrum, attached to the sacrum by a fibrocartilaginous joint, the sacrococcygeal symphysis

The epoophoron or epoöphoron (also called organ of Rosenmüller or the parovarium; : epoophora) is a remnant of the mesonephric duct that can be found next to each ovary, and fallopian tube.

The paroophoron (of Johnson; : paroophora) consists of a few scattered rudimentary tubules, best seen in a child, situated in the broad ligament between the epoöphoron and the uterus. Named for the Welsh anatomist David Johnson who originally described the structure at the University of Wales, Aberystwyth.
