Coccyx Anatomy

It is composed of three to five successively smaller caudal coccygeal vertebrae. The coccyx is located at the distal tip of the sacrum and is the most distal portion.

Anatomy Sacrum And Coccyx 3d Model

Later in life the coccyx may fuse with the sacrum though this is more common in women than in men.

Coccyx anatomy. This is a type of joint that functionally only allows for a slight amount of movement. The coccyx also known as the tailbone is the terminal part of the vertebral column. Coccyx also called tailbone curved semiflexible lower end of the backbone vertebral column in apes and humans representing a vestigial tail.

In this article we will discuss the anatomy of the coccyx its structure bony landmarks ligaments and clinical relevance. As mentioned above the coccyx is usually comprised of. It is a vestige of the caudal vertebrae found in the tails of most mammals.

It is comprised of four vertebrae which fuse to produce a triangular shape. The coccyx serves as an attachment site for tendons ligaments and muscles. Anatomy of the coccyx tailbone the coccyx usually moves slightly forward or backward as the pelvis hips and legs move.

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. 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. The coccyx is connected to the sacrum by means of an amphiarthrodial joint.

The coccyx is an inverted triangle with the base wide part at the top and the apex pointy end. The coccyx or tailbone is both the smallest and the most inferior bone in the spinal column.
