What is the Intermediolateral nucleus?
Intermediolateral nucleus (IML) is located in the intermediate zone between the dorsal and the ventral horns in the spinal cord, extending from C8 or T1 to L1 spinal cord segments. It contains the preganglionic sympathetic neurons of the spinal cord.
What is an Intermediolateral cell column?
intermediolateral nucleus the cell column that forms the lateral horn of the spinal cord’s gray matter. Extending from the first thoracic through the second lumbar segment, the column contains the autonomic motor neurons that give rise to the preganglionic fibers of the sympathetic system.

Where is Clarke’s column?
the spinal cord

What are Rexed laminae?
Definition. Rexed’s laminae is an architectural classification of the structure of the spinal cord, based on the cytological features of the neurons in different regions of the gray substance described by the Swedish Anatomist B. Rexed.

Where is the cuneate nucleus?
medulla oblongata
The external cuneate nucleus is located in the dorsolateral part of the medulla oblongata at the level of the inferior olivary nucleus. The nucleus contains widely scattered, large neurons.
