The correct spelling of the word "coccyx" is often a source of confusion. The reason for this is its unique pronunciation, which is not always reflected in its spelling. The word is pronounced /ˈkɒksiks/, with the emphasis on the first syllable. It is spelled with a double "c" followed by a "y" and another "c" preceding the final "x". This unusual combination of letters can be challenging for many people to remember, but it is important for medical professionals and individuals studying anatomy to be familiar with the correct spelling and pronunciation of the word.
The coccyx, also known colloquially as the tailbone, is a small, triangular bone located at the base of the vertebral column in humans and several other mammals. It consists of three to five fused or partially fused vertebrae that gradually decrease in size from top to bottom. The coccyx is positioned beneath the sacrum bone and curves slightly inward, pointing towards the pelvis.
Acting as an attachment site for various ligaments, tendons, and muscles, the coccyx plays a crucial role in supporting the weight of the body and maintaining overall stability. It serves as an anchor point for several important structures, including the gluteus maximus muscles and the pelvic floor muscles.
Although the coccyx is considered a vestigial structure with no significant purpose, it can be subjected to trauma or injury due to its vulnerable position. Falls on the buttocks, childbirth, and repetitive strain from activities such as biking can lead to coccyx pain, known as coccydynia. This condition can cause discomfort, tenderness, and difficulties with sitting or moving the lower back.
In conclusion, the coccyx is a small, triangular bone located at the base of the spine, formed by the fusion of several vertebrae. While it may not have a primary function, it serves as an attachment site for various structures and can experience pain and discomfort due to injury or strain.
Os coccygis, the small bone at the end of the spinal column in man, formed by the fusion of four rudimentary vertebrae; it articulates above with the sacrum.

The word "coccyx" is derived from the Greek "kokkux" meaning "cuckoo" or "cuckoo's beak". This is due to the resemblance of the coccyx to the shape of a cuckoo's beak.
