Let's take a look at the terrestrial biomes. The coldest biome is called the tundra. It is located at the North (Arctic) and South (Antarctic) Poles. An alpine tundra is also found on top of mountains at very high elevations.
Peroneal neuropathy refers to an impairment of the peroneal nerve. It is the most common neuropathy of the lower extremities. The common peroneal nerve is the most common nerve in the body to be injured as the result of trauma. It can be injured by trauma to the knee or to the thigh.
This would be where you use the example of the peroneal nerve. This nerve is away from the spinal root and would then be classified as a neuropathy. If a nerve is affected at the horn level it would be a problem called a motor nerve problem such as ALS or MS. Hope that clears things up. Remember where the problem is found is where it is named.
