What is a coccygeal vertebra?

The coccygeal vertebrae are the four smallest and most inferior (lowest) vertebrae of the vertebral column. They are fused together to form a triangular bone called the coccyx. The coccyx is located at the base of the spine, just below the sacrum.

The coccygeal vertebrae are often referred to as the tailbone. This is because they are the remnants of the tailbone that is present in most other mammals. In humans, the coccyx is vestigial, meaning that it has no apparent function. However, it does provide some support for the pelvic floor and the rectum.

The coccyx is also the site of attachment for several muscles and ligaments. These muscles and ligaments help to stabilize the pelvis and the spine.

The coccyx can be injured in a variety of ways, including falls, sports injuries, and childbirth. Injuries to the coccyx can cause pain, bruising, and swelling. In some cases, coccygeal injuries can also lead to nerve damage and incontinence.

Treatment for coccygeal injuries typically involves rest, ice, and pain medication. In some cases, surgery may be necessary to correct severe injuries.
