Häntäluussa

Häntäluussa, also known as the coccyx, is the final section of the vertebral column in humans and many other primates. It is located at the very end of the spine, below the sacrum. The coccyx typically consists of three to five fused vertebrae, although the number can vary.

The coccyx is a vestigial structure, meaning it is a remnant of the tail that our primate ancestors possessed. While it no longer serves the function of a tail, it still plays a role in human anatomy. It serves as an attachment point for various muscles, ligaments, and tendons, including those that help support pelvic floor muscles. These muscles are important for bowel and bladder control, as well as sexual function.

Pain in the coccyx, known as coccydynia, can occur due to injury, such as a fall, or from prolonged sitting on hard surfaces. It can also be associated with childbirth or certain medical conditions. Treatment for coccydynia often involves pain management, physical therapy, and lifestyle modifications. In rare cases, surgery may be considered. The coccyx, despite its small size and vestigial nature, is an integral part of the skeletal structure and contributes to overall pelvic stability and function.
