Verified step by step guidance

Understand the structure of the spinal cord: The spinal cord is divided into regions - cervical, thoracic, lumbar, sacral, and coccygeal. Each region has specific functions and structures.

Identify the sympathetic nervous system's role: The sympathetic nervous system is part of the autonomic nervous system responsible for the 'fight or flight' response. It involves preganglionic and postganglionic fibers.

Locate the lateral horn: The lateral horn is a specific area within the spinal cord where sympathetic preganglionic neurons are found. It is present in the thoracolumbar region, which includes the thoracic and lumbar segments.

Differentiate between the horns: The spinal cord has dorsal, ventral, and lateral horns. The dorsal horn is associated with sensory processing, the ventral horn with motor control, and the lateral horn with autonomic functions.

Conclude the location: Based on the understanding of spinal cord anatomy and the function of the sympathetic nervous system, the cell bodies of sympathetic preganglionic fibers are located in the lateral horn of the thoracolumbar region.
