The spinal column has two ends. At the top, it ends in the skull, and at the bottom, it ends in the coccyx.

Because the neck is relatively fragile compared with the rest of the spine ... and it has that big lump at the top end.
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.
In the cervical and thoracic area of your spine. The cervical vertebrae starts right under your skull (following what's called the occipital foramen/foramen magnum). There are 7 cervical verterbrae and they end aproximatively under your neck (in the place where you feel a small circular prominence). Right under there are the thoracic vertebrae, in the number of 12. They end, let's say, at the upper part of your lower back.
The inferior end would refer to the top of the sacrum because inferior means situated above. ===== Actually, inferior would be the bottom end. Superior is the to end.
The body of each vertebra is attached to a bony ring consisting of several parts. A bony projection on either side of the vertebral body called the pedicle supports the arch that protects the spinal canal. The laminae are the parts of the vertebrae that form the back of the bony arch that surrounds and covers the spinal canal. There is a transverse process on either side of the arch where some of the muscles of the spinal column attach to the vertebrae. The spinous process is the bony portion of the vertebral body that can be felt as a series of bumps in the center of a person's neck and back.
answer me!!!!!!!!!!!!!!!!!!gosh!!!!!!!!
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.

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.
