Which field of study focuses on the nervous system?

The field of study that focuses on the nervous system is neurology. Neurology is a branch of medicine that deals specifically with the diagnosis and treatment of disorders affecting the nervous system, which includes the brain, spinal cord, and peripheral nerves. Neurologists study various conditions such as strokes, epilepsy, multiple sclerosis, and Parkinson's disease, among others. This specialization requires an in-depth understanding of the structure and function of the nervous system, making it the most relevant field compared to the other options.

While psychology examines behavior and mental processes, which are influenced by the nervous system, it does not exclusively focus on the biological aspects of the nervous system itself. Anatomy, on the other hand, is the study of the structure of body parts and systems but encompasses all body systems, not just the nervous system. Physiology studies the functions of the various body parts and systems, including how the nervous system operates, but it is more about the functions rather than the structures themselves. Therefore, neurology is the most precise field dedicated specifically to the nervous system.
