In medicine, neurology is the study of nerves and the nervous system. A medical student who is interested in neurology will learn about strokes, epilepsy, and other nervous system disorders.
The nervous system is made up of the brain, spinal cord, nerves, and ganglia throughout the body. Neurology involves the structure and function of these parts, and it also investigates diseases and disorders involving them. Because the brain is part of the nervous system, this includes brain trauma or dysfunction (like memory loss, concussions, and seizures). Neurology comes from the Greek neurologia, or "study of nerves."
