Which statement accurately describes the conus medullaris?Multiple choice question.A structure made of the axons of motor and sensory neurons that resembles a horse's tail.The tapered end of the spinal cord is just inferior to the lumbar enlargement.The portion of the spinal cord that emerges through the foramen magnum
Solution
The statement that accurately describes the conus medullaris is: "The tapered end of the spinal cord is just inferior to the lumbar enlargement."
The conus medullaris is the terminal end of the spinal cord, which typically occurs near the first lumbar vertebra. It is not the structure made of the axons of motor and sensory neurons that resembles a horse's tail - that's the cauda equina. Also, it is not the portion of the spinal cord that emerges through the foramen magnum - that's the brainstem.
