What is neuritis?

Neuritis is specifically defined as inflammation of a nerve. This condition can result from various factors, including infections, autoimmune diseases, trauma, or exposure to toxins. The inflammation can lead to symptoms such as pain, tingling, numbness, or weakness in the areas supplied by the affected nerve.

While the other options describe different medical conditions or concepts, they do not accurately define neuritis. Inflammation of muscle tissue pertains to conditions like myositis, damage to nerve pathways would refer to processes like neuropathy or nerve injuries, and a neurological disorder encompasses a broader range of illnesses affecting the nervous system but does not pinpoint the specific inflammatory aspect that characterizes neuritis. Thus, inflammation of a nerve is the precise definition that distinguishes neuritis from other conditions related to the nervous system.
