Question

If semifluid nucleus pulposus of intervertebral disk enters the vertebral canal, it will lead to

• A. Compression of spinal cord
• B. Compression of nerve roots
• C. Neurologic disturbances
• D. All of the above

Answer 1

The correct option is D All of the above

There are intervertebral discs between the adjacent vertebrae. The disc forms a fibrocartilaginous joint. The discs consists of an outer fibrous ring which is called the anulus fibrosus. This surrounds the inner gel-like center which is called as the nucleus pulposus. The nucleus pulposus contains loose fibers which are suspended in a mucoprotein gel. The nucleus of the disc acts as a shock absorber. If this enters the vertebral canal, then it may lead to various neurologic disorders and also compression of nerve roots and spinal cord.
Thus, the correct answer is option D.
