What is another word for coccyx?
Pronunciation: [kˈɒkɪks] (IPA) 
The coccyx, also known as the tailbone, is a small triangular bone located at the base of the spine. While often referred to by its scientific name, there are several synonyms that can be used to describe this bone, including coccygeal bone, caudal vertebrae, or the terminal vertebrae of the spine. Additionally, some may refer to the coccyx as the tail end or simply the tail, as it is homologous to the tails of other animals. Despite its small size, the coccyx plays an important role in supporting the weight of the body while sitting and also serves as a site for muscle and ligament attachment.
