Verified step by step guidance

Understand the role of preganglionic sympathetic neurons: These neurons are part of the autonomic nervous system and are responsible for transmitting signals from the central nervous system to the sympathetic ganglia.

Recall the anatomy of the spinal cord: The spinal cord is divided into regions—cervical, thoracic, lumbar, sacral, and coccygeal. Each region has specific functions and structures associated with it.

Learn the location of sympathetic nervous system components: Preganglionic sympathetic neurons originate in the lateral horn of the spinal cord, specifically in the thoracic and upper lumbar regions (T1-L2). This is known as the thoracolumbar division of the autonomic nervous system.

Eliminate incorrect options: The sacral region is associated with the parasympathetic division, not the sympathetic division. The cervical and coccygeal regions do not contain preganglionic sympathetic neurons.

Conclude that the thoracic and upper lumbar regions are the correct answer because they house the cell bodies of preganglionic sympathetic neurons in the lateral horn of the spinal cord.
