Final answer:
The false statement when comparing the ANS to the somatic system is that it is located in the ventral gray horn. The ventral gray horn is associated with the somatic nervous system. ANS features include divisions into sympathetic and parasympathetic systems, with differing lengths and myelination patterns of their fibers.
Step-by-step explanation:
The autonomic nervous system (ANS) compared to the somatic system is: Located in ventral gray horn (b). The ventral gray horn pertains to the somatic nervous system, where the cell bodies of motor neurons that innervate skeletal muscle are found.
The ANS is characterized by its two main divisions: the sympathetic nervous system and the parasympathetic nervous system. The preganglionic fibers of the sympathetic division tend to be short and myelinated, while the postganglionic fibers are long and typically unmyelinated. This is in contrast to the parasympathetic division, where preganglionic fibers are long and postganglionic fibers are short, reflecting the location of the ganglia near or within the target organs.
The preganglionic fibers in both sympathetic and parasympathetic systems are myelinated B fibers, and the postganglionic fibers are generally unmyelinated C fibers. Finally, the ratio of postganglionic to preganglionic fibers can be quite high, as a single preganglionic fiber can branch to innervate multiple postganglionic neurons, although the exact ratio can vary.
