Where are intervertebral discs located?

• A. Between the bodies of adjacent vertebrae
• B. Between laminae
• C. Between the arches
• D. Inside the spinal canal

Answer: (A)

Intervertebral discs are located between the bodies of adjacent vertebrae. They sit in the intervertebral spaces, separating one vertebral body from the next, and lie in front of the spinal canal. This position allows them to absorb compressive loads and enable small movements between vertebrae, due to their structure of an inner nucleus pulposus and an outer annulus fibrosus. They are not found between laminae or arches, and they are not inside the spinal canal.
