The coccyx, or tailbone, resides at the end of the vertebral column in humans. It is a small triangular bone that consists of three to five fused vertebrae and provides attachment for various muscles and ligaments.
The vertebrae at the end of the spine are fused to form the coccyx (tailbone).
There are 33 vertebrae in the spinal cord of a human being. They are broadly categorized into 5 areas. They are called the cervical, thoracic, lumbar, sacrum & coccyx vertebra. The upper 3 areas have a total of 24 vertebrae, which includes 7 cervical vertebrae, 12 thoracic vertebrae & 5 lumbar vertebrae. Sometimes the lumbar region, may have an additional vertebra, it does happen - but it is rare. 5 vertebrae are fused together to form the sacrum & 3 vertebrae form the end of the spinal column which is the coccyx.

Cervical vertebrae possess transverse foramina to allow for the vertebral arteries to pass through on their way to the foramen magnum to end in thecircle of Willis.

This is a tricky question as it is not clear which end of the spine we are referring to. At the head end there is a bone or vertebra upon which the head is resting this is known as the atlas, it does not have a body and its centrum fuses with the axis to provide a pivot for the head to turn on. At the other end of the spine - the tail end the last bones are fused together to form the coccyx, the number may vary from 3 to 5. These bones are rudimanetary and are usually fused together.
The cervical bones (1-5) run from the base of the skull to the bottom of the neck, roughly. The thoracic vertebrae (1-12) run from the end of the cervical spine to the lumbar spine. The lumbar vertebrae (1-5) run from the end of the thoracic spine to the tailbone.
