Multiple sclerosis is a condition characterized by inflammatory, demyelinating lesions in the central nervous system separated in space and time.

Agents are also referred to as real estate associates. A realtor is a real estate agent who is a member of the National Association of Realtors (NAR). To become a member, a real estate agent has to agree to abide by the association's standards and uphold its code of ethics.
When a seller hires a real estate broker to list her property for sale, the seller becomes that broker's client. A client, in real estate parlance, is the person whose interests the broker represents, so the broker is the seller's agent. The real estate agents who work for the broker, or who work under the broker by assisting the buyer, are often known as subagents. Subagents work for the seller, just as the broker does.
