<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 21-year-old man was involved in a motor vehicle accident and died. At autopsy, the patient demonstrated abnormally increased mobility at the neck. A section of cervical spinal cord at C6 was removed and processed into slides. Which of the following gross anatomic features is most likely true of this spinal cord level?? A: Prominent lateral horns, B: Least amount of white matter, C: Absence of gray matter enlargement, D: Involvement with parasympathetic nervous system, E: Cuneate and gracilis fasciculi are present,  <response>: This is a question about the gross anatomy of the cervical spinal cord. Based on the information provided, the patient died from a motor vehicle accident and had increased mobility of the neck, suggesting a spinal cord injury at the C6 level. The choices describe different anatomical features that may be present at this spinal cord level. Choice A describes the lateral horns, which are most prominent in the thoracic and upper lumbar spinal cord, not cervical. Choice B is incorrect because the cervical spinal cord has more white matter than lower levels. Choice C is incorrect because there are gray matter enlargements in the cervical cord. Choice D is irrelevant since the parasympathetic nervous system is not directly associated with the spinal cord. Choice E is correct. The cuneate and gracilis fasciculi, which carry information from the upper body and arms, are present at the C6 spinal cord level. This is the only choice consistent with the expected anatomy at this level.E: Cuneate and gracilis fasciculi are present
