Which term describes the growth of tumors on the nerves?

The term that describes the growth of tumors on the nerves is neurofibromatosis. This condition is characterized by the development of multiple benign tumors called neurofibromas, which originate from the nerve sheath. Neurofibromatosis is a genetic disorder that affects the growth and development of nerve tissues, leading to a variety of neurological symptoms and complications.

Other choices refer to different medical conditions: sarcoma is a type of cancer that originates in connective tissues like bone, fat, or muscle; fibromyalgia is a chronic pain condition that affects the muscles and soft tissues, leading to widespread pain and fatigue; and neuropathy refers to damage or dysfunction of one or more peripheral nerves, commonly resulting in weakness, numbness, or pain. None of these terms specifically describes the formation of tumors on nerves, which is why neurofibromatosis is the correct answer.
