Neurology is the study of which of the following?

Neurology is indeed focused on the structure and function of the nervous system. This field encompasses the study of the brain, spinal cord, and peripheral nerves, including their roles in controlling bodily functions, behavior, and cognitive processes. Understanding neurology is essential for recognizing how the nervous system influences every aspect of human health, from reflexes and movement to emotion and thought processes.

The other options pertain to different fields of study. The digestive system is the focus of gastroenterology, the skin and its functions relate to dermatology, and the reproductive system falls within the scope of gynecology and urology. Each of these areas requires specialized knowledge distinct from neurobiology, highlighting why neurology is specifically dedicated to the nervous system's complexities.
