Question: Neurons with cell bodies in the intermediolateral cell column at the T4 level of the spinal cord send their axons to which of the following structures or pathways?

Options:

• Cuneate nucleus
• Parasympathetic ganglia
• Reticulospinal tract
• Sympathetic chain ganglia

Correct Answer: Sympathetic chain ganglia

Explaination: The intermediolateral cell column contains cell bodies of neurons in the autonomic nervous system (sympathetic neurons at the C8 to L3 levels and parasympathetic neurons at the S2 to S4 levels). Neurons in the thoracic posterior nucleus (Clarke nucleus) project to the cerebellum via the spinocerebellar tract. Neurons projecting to the cuneate nucleus have their cell bodies in the dorsal root ganglion, and the reticulospinal tract originates in the brainstem
