Solution
The answer to Question 4 is: both the brain and the lateral gray horns of the spinal cord.
Explanation:
The autonomic nervous system (ANS) is divided into the sympathetic and parasympathetic nervous systems.
Preganglionic neurons of the sympathetic nervous system emerge from the lateral gray horns of the spinal cord, specifically from the thoracolumbar region (T1 to L2).
Preganglionic neurons of the parasympathetic nervous system emerge from the brain (cranial nerves III, VII, IX, and X) and the sacral region of the spinal cord (S2 to S4).
Therefore, preganglionic neurons of the ANS emerge from both the brain and the lateral gray horns of the spinal cord.
For Question 5, the question is incomplete, so I cannot provide an accurate answer.
