Coccyx anatomy. The coccyx is connected to the sacrum by means of an amphiarthrodial joint. This is a type of joint that functionally only allows for a slight amount of movement. When a person sits or stands the bones that make up the pelvis including the coccyx rotate outward and inward slightly to better support and balance the body.

As mentioned above the coccyx is usually comprised of. The coccyx is an inverted triangle with the base wide part at the top and the apex pointy end. In the human body the coccyx functions to anchor several muscles of the pelvic region and acts as one of the bones that bear the bodys weight while sitting.

The coccyx is located at the distal tip of the sacrum and is the most distal portion. Coccyx also called tailbone curved semiflexible lower end of the backbone vertebral column in apes and humans representing a vestigial tail. It is comprised of four vertebrae which fuse to produce a triangular shape.

Anatomy of the coccyx tailbone the coccyx usually moves slightly forward or backward as the pelvis hips and legs move. It is composed of three to five successively smaller caudal coccygeal vertebrae.
