Options:
- Nerve fibers covered with myelin sheaths
- Nerve cell bodies covered with myelin sheaths
- Nerve fibers not covered with myelin sheaths
- Nerve cell bodies not covered with myelin sheaths
Answer:
- Nerve fibers not covered with myelin sheaths
Step-by-step explanation:
Myelin causes electrical information to travel rapidly from one neuron to another, lining its axons. In the brain, the white matter is located below the gray matter, which is the cerebral cortex. In the spinal cord, it is on the outside, covering the gray matter.
