In humans, the coccyx, also known as the tailbone, is formed by the fusion of multiple vertebrae. Among the following options, determine the accurate number of vertebrae involved in this fusion:
Three vertebrae
Four vertebrae
Five vertebrae
Six vertebrae
The coccyx in humans is formed by the fusion of four vertebrae. It is the remnant of a tail that our ancestors had. The fusion of these four small vertebrae creates the triangular-shaped coccyx, located at the bottom of the vertebral column.Hence, the correct answer is option 2.
