ANATOMY

Detailed explanation-1: -Your coccyx is made up of three to five fused vertebrae (bones). It lies beneath the sacrum, a bone structure at the base of your spine. Several tendons, muscles and ligaments connect to it.

Detailed explanation-2: -Below the sacrum is the coccyx, commonly known as the tailbone. The coccyx, like the sacrum, is a set of fused bones, though four bones make up the coccyx. It serves as an attachment point for a number of pelvic and hip tendons.

Detailed explanation-3: -Sometimes the cause is unknown, but common causes include injury from falls or childbirth infections or sitting too long on a hard surface. It’s rare, but tailbone pain may be caused by cancer. It may be bone cancer or another type that spreads to into your bone, which is called metastatic cancer.

Detailed explanation-4: -Location. The coccyx is located at the distal tip of the sacrum and is the most distal portion of the spinal column. The base of the coccyx articulates with the apex of the sacrum. Some articulation is possible between coccygeal vertebrae until they are fused, but they do not move very much.

Detailed explanation-5: -Despite its small size, the coccyx has several important functions. Along with being the insertion site for multiple muscles, ligaments, and tendons, it also serves as one leg of the tripod-along with the ischial tuberosities-that provides weight-bearing support to a person in the seated position.
