Which statement correctly describes the intermediolateral cell column?

Which statement correctly describes the intermediolateral cell column?

• A. Axons that originate from postganglionic neurons outside the spinal cord
• B. Axons that connect preganglionic autonomic neuronal cell bodies within the spinal cord and a visceral root
• C. Axons carrying somatic motor fibers to muscles
• D. Axons forming the dorsal column

Answer: (B)

The key idea is that the intermediolateral cell column contains the cell bodies of preganglionic sympathetic neurons. Their axons exit the spinal cord through the ventral roots and join visceral nerves to reach autonomic ganglia, forming the pathway that connects spinal cord–level autonomic neurons to the sympathetic chain and beyond. This makes the description of axons that connect preganglionic autonomic neuronal cell bodies within the spinal cord and a visceral root the correct one. The other statements describe postganglionic fibers outside the cord, somatic motor fibers in the ventral horn, or sensory fibers in the dorsal column, which do not pertain to the intermediolateral cell column.
