Why are ruptured intervertebral discs more common in lumbar vertebrae and dislocations and fractures more common in cervical vertebrae?
What will be an ideal response?
The lumbar vertebrae have massive bodies and carry a lot of weight; these factors contribute to the rupturing of an intervertebral disc. The cervical vertebrae are more delicate and have small bodies; these factors increase the possibility of dislocations and fractures in the cervical vertebrae. In addition, the cervical vertebrae are more mobile and are not as well protected.
