What is the main purpose of the coccyx?

The main purpose of the coccyx, commonly known as the tailbone, is to provide attachment points for various muscles, ligaments, and tendons. This small, triangular bone at the base of the vertebral column plays a crucial role in maintaining pelvic stability and supporting the weight of the body when sitting. It acts as an anchor for these soft tissues, which contribute to the movement and function of the pelvic region.

While it is true that the coccyx does assist in some form of support for the lower torso and could be considered to play a minor role in protecting some structures, its primary function is indeed to serve as an attachment point for muscles and ligaments. This role underlies its importance in human anatomy and movement.
