Which term refers to the intervertebral disk?

• A. Disc
• B. Distal
• C. Dorsal
• D. Dupuytrens contracture

Answer: (A)

The intervertebral structure is a disc, the cushion between adjacent vertebrae that helps absorb shock and allow movement. It consists of an outer ring called the annulus fibrosus and a soft center called the nucleus pulposus. The other options describe entirely different ideas: distal means farther from the center or a point of reference; dorsal means the back side of the body; and Dupuytren's contracture is a hand condition affecting the palmar fascia. So the correct term for the intervertebral structure is disc, with the common anatomical spelling being disc rather than disk.
