Question

Quizplus · Accepted Answer

Cutting of the dorsal root of a spinal nerve is called rhizotomy. It is a surgical procedure that is performed to relieve pain caused by conditions such as herniated discs or arthritis. Rhizotomy is not the same as vagotomy or phrenemphraxis, which involve cutting or blocking nerves that control other functions, such as digestion or breathing. Lumbar puncture, on the other hand, is a diagnostic procedure that involves inserting a needle into the lower spine to collect cerebrospinal fluid for testing. It is not a treatment for pain.
