The intermediolateral nucleus (IML) is a region of gray matter found in Rexed lamina VII of the spinal column.
Rexed Lamina VII contains several well defined nuclei including the nucleus dorsalis (Clarke's column), the intermediolateral cell column (lateral gray horn), and the sacral autonomic nucleus.
It extends from the first thoracic through the second lumbar segment, and contains the autonomic motor neurons that give rise to the preganglionic fibers of the sympathetic system. (Preganglionic sympathetic general visceral efferent)
Also known as Lateral Gray Horn.
