Explanation:

Epidural anesthesia is a type of regional anesthesia. It is used to block pain in a particular region of the body. It works by injecting an anesthetic agent into the epidural space. This blocks the nerve impulses from the lower part of the body. However, it does not completely block motor functions like some other types of anesthesia (e.g., general anesthesia). So, it blocks pain but preserves some motor function.
The option "blocks both sensory and motor functions" is more characteristic of general anesthesia. The option "is a medical procedure performed to collect cerebrospinal fluid for diagnostic purposes" describes a lumbar puncture. The option "is when an anesthetic agent is injected directly into the cerebrospinal fluid at the lower lumbar level" describes spinal anesthesia.

Answer:

blocks pain but preserves some motor function.
