Question

preganglionic neurons of the sympathetic nervous system are located in the
lateral gray horns of t₁ to s₂ of the spinal cord.
anterior gray horns of the cervical and thoracic spinal cord.
lateral gray horns of segments t₁ to l₂ of the spinal cord.
anterior gray horns of segments t₁ to l₂ of the spinal cord.
lateral gray horns of the cervical cord.

Explanation:

The sympathetic nervous system's preganglionic neurons are located in the lateral gray horns. The spinal cord segments for the sympathetic preganglionic neurons are from T₁ (thoracic 1) to L₂ (lumbar 2). The anterior gray horns are mainly for somatic motor neurons. The S₂ (sacral 2) is related to the parasympathetic system (part of the craniosacral outflow for parasympathetic, while sympathetic is thoracolumbar - T₁ - L₂). The cervical cord (for the options given) is not the location for sympathetic preganglionic neurons in terms of the standard anatomical location of sympathetic preganglionic cell bodies.

Answer:

lateral gray horns of segments T₁ to L₂ of the spinal cord.
