Detailed explanation-1: -The coccyx is a triangular bone that consists of 3 to 5 fused segments, the largest of which articulates with the lowest sacral segment. In addition, the first coccygeal segment contains rudimentary articular processes called the coccygeal cornua that articulate with the sacral cornua.

Detailed explanation-2: -Listen to pronunciation. (TAYL-bone)

Detailed explanation-3: -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-4: -Tailbone pain-pain that occurs in or around the bony structure at the bottom of the spine (coccyx)-can be caused by trauma to the coccyx during a fall, prolonged sitting on a hard or narrow surface, degenerative joint changes, or vaginal childbirth.
