The tailbone on a human, also known as the coccyx, is a vestigial structure, meaning it is the remains of a body part that we once may have had during the process of evolution. Just like its name implies, the tailbone could very well have been a tail at one time, but it is unclear how long it would have developed or grown. As humans began to travel and use two feet, a tail would have became useless and shrunk over time. Although this has not been proven, it is a possible theory for the existence of the human tail bone.
Today, the tail bone serves as a support structure for muscles and acts as a shock absorber when sitting. Non (Evolution Theory) Purpose of the coccyx. The Coccyx is an important attachment for various muscles, tendons and ligaments --- which makes it necessary for physicians and patients to pay special attention to these attachments when considering surgical removal of the coccyx. Additionally, it is also part of the weight bearing tripod structure which act as a support for a sitting person. When a person sits leaning forward, the ischial tuberosities and inferior rami of the ischium take most of the weight, but as the sitting person leans backward, more weight is transferred to the coccyx. The anterior side of the coccyx serves for the attachment of a group of muscles important for many functions of the Pelvic floor ( Example... Defication,Continence etc..)The levator- ani muscle which include coccygeus iliococcygeus, and pubococcygeus. Through the anococcygeal raphe, the coccyx supports the position of the anus. Attached to the posterior side is gluteus maximus which extend the thigh during ambulation. Many important ligaments attach to the coccyx: The anterior and posterior sacrococcygeal ligaments are the continuations of the anterior and posterior longitudinal ligaments that stretches along the entire spine. Additionally, the lateral sacrococcygeal ligaments complete the foramina for the last sacral nerve. And, lastly, some fibers of the sacrospinous and sacrotuberous ligaments (arising from the spine of the ischium and the ischial tuberosity respectively) also attach to the coccyx.
