Question

The coccyx is also the result of the fusion of vertebrae. The combining form coccyg/o means coccyx, or tail bone. This is located at the base of the spinal column and represents four fused coccyg+eal bones (-eal means pertaining to). The coccyx is the result of fusion of four _____ bones.

Answer 1

The coccyx, or tailbone, is formed by the fusion of four coccygeal vertebrae which provide attachment points for ligaments and muscles, serving important support and stabilization functions for the vertebral column.

Step-by-step explanation:

The coccyx, also known as the tailbone, is the small bone located at the inferior end of the adult vertebral column and is comprised of four coccygeal vertebrae that have fused together. These four bones are not weight bearing when standing, but they may receive some body weight while sitting. The coccyx articulates with the sacrum, and it typically begins to form through the fusion of these vertebrae after the age of 20.

Not only does the coccyx provide attachment points for ligaments and muscles, but it's also a remnant of a tail-like structure that our ancestors had. Because of its resemblance and position in the vertebral column, it is colloquially referred to as the 'tailbone'. The fusion of the coccygeal vertebrae helps to stabilize our vertebral column, serving important functions in terms of support and attachment.
