Question:

What is the function of the coccyx (tail bone)?

Answer:

The coccyx doesn't really serve a purpose in itself. It does, however, serve as an attachment site for muscles and ligaments.

coccyx Anatomy

The human body is the entire structure of a human organism and comprises a head, neck, torso, two arms and two legs. By the time the human reaches adulthood, the body consists of close to 100 trillion cells, the basic unit of life. These cells are organised biologically to eventually form the whole body.

Anatomy (from the Greek ἀνατέμνωanatemnō, "I cut up, cut open" from ἀνά – ana, "on, upon", and τέμνω – temnō, "I cut") is the study of the body plan of animals. In some of its facets, anatomy is closely related to embryology, comparative anatomy and comparative embryology, through common roots in evolution. Human anatomy is important in medicine.

The discipline of anatomy is subdivided into gross (or macroscopic) anatomy and microscopic anatomy. Gross anatomy is the study of structures that can, when suitably presented or dissected, be seen by unaided vision with the naked eye. Microscopic anatomy is the study of structures on a microscopic scale, including histology (the study of tissues) and cytology (the study of cells).

Zoology

The vertebral column, also known as backbone or spine, is a bony structure found in vertebrates. It is formed from the vertebrae.

Tail

The pubococcygeus muscle or PC muscle is a hammock-like muscle, found in both sexes, that stretches from the pubic bone to the coccyx (tail bone) forming the floor of the pelvic cavity and supporting the pelvic organs. It is part of the levator ani group of muscles.

A coccyx fracture is a fracture of the coccyx, commonly called a 'broken tailbone'.

The coccyx is located at the base of the spine, under the sacrum. It is the last section of the ape vertebral column. Most commonly in humans it comprises 3 to 5 fused (or, more rarely, separate) vertebrae, and is approximately 4 to 10 cm in length. The coccyx is attached to the sacrum by a fibrocartilaginous joint, called the sacrococcygeal symphysis, allowing for some (but little) movement.
