How the Tail Works
The tail is an extension of the spine, but it’s more mobile and flexible. A wedgelike bone at the base of the spine known as the sacrum anchors the tail. The subsequent tailbones (coccygeal, or caudal, vertebrae) get smaller and smaller along the length of the tail. Cushioning each tailbone are tiny joints and disc pads. Muscles put the wag in the tail and play a role in faecal control. Blood vessels and nerves are also part of the tail’s anatomy.
When the tail is injured, the damage can be as simple as the “Ouch!” from getting the tip caught in a doorway or as serious as heavy bleeding or severe nerve damage. The tail is prone to injury because it’s unprotected and frequently in motion.
