Final answer:
Neuropathy is the term that describes a disorder of several peripheral nerves. It can cause symptoms like numbness and weakness. It is distinct from central nervous system disorders like multiple sclerosis, which affects the myelin sheath of nerve fibers.
Step-by-step explanation:
A general term describing a disorder of several peripheral nerves is neuropathy. This term refers to various conditions that involve damage to the peripheral nerves, which can result in symptoms such as numbness, tingling, pain, and weakness, often in the hands and feet. Neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, and multiple sclerosis (MS) also fall into the category of neurological disorders, with MS specifically affecting the myelin sheath that covers nerve fibers, leading to symptoms like fatigue, vision problems, and loss of balance.
