Dorsal median sulcus is a groove on which surface of the spinal cord?

• A. Dorsal surface
• B. Central canal region
• C. Ventral surface
• D. Lateral surface

Answer: (A)

This question focuses on surface anatomy of the spinal cord. The dorsal median sulcus is a shallow groove that runs along the midline on the back (dorsal) surface of the spinal cord, helping to separate the dorsal columns. It’s a surface feature on the posterior aspect, not inside the central canal or on the ventral or lateral surfaces. So the groove is on the dorsal surface.
