coccygealryhmä

The term "coccygealryhmä" is a Finnish word that translates to "coccygeal group" in English. It refers to the collection of bones that form the human tailbone, also known as the coccyx. This group of bones is located at the very end of the vertebral column, below the sacrum.

The coccygeal group typically consists of three to five fused vertebrae. The exact number can vary among individuals. These vertebrae are small and rudimentary, lacking the distinct features of the larger vertebrae found higher up in the spine. They are connected to the sacrum by a joint that allows for slight movement, though this mobility is generally limited in adults.

The coccyx serves several functions. It acts as an attachment point for several muscles, ligaments, and tendons, including those of the pelvic floor. These structures play a role in posture, defecation, and sexual function. While humans do not have a tail, the coccyx is considered a vestigial remnant of the tail present in our evolutionary ancestors. Injury to the coccygeal group can result in pain, a condition known as coccydynia.
