The nervous system controls and regulates activity and movement in the body. If the nervous system is not functioning properly, the body cannot function. It is the job of a neurologist to find and correct any problems in the nervous system.

A nurse practitioner is a registered nurse who has gone through additional training to provide more advanced medical and diagnostic care to patients with all different kinds of illnesses.
