Which health professional treats diseases/disorders primarily related to the nervous, muscular, and skeletal systems?

The correct answer is Doctor of Chiropractic (DC) because this professional specializes in diagnosing and treating conditions related to the nervous, muscular, and skeletal systems, particularly those involving the spine. Chiropractors focus on the body's alignment and how it affects overall health, employing techniques like spinal manipulation to alleviate pain and improve function. Their training emphasizes the relationship between the spine and the nervous system, which is central to their treatment philosophy.

Other health professionals, while also addressing aspects of health related to the systems mentioned, have different primary focuses. For instance, a Doctor of Medicine (MD) and a Doctor of Osteopathic Medicine (DO) are trained to manage a wide range of health issues, including medical and surgical interventions across various systems of the body, not just the musculoskeletal system. A Doctor of Podiatry (DPM) specializes in conditions specifically affecting the feet and ankles, which is a narrower scope of practice compared to chiropractic care. Therefore, the unique focus of chiropractors on the interplay between the nervous and musculoskeletal systems makes the Doctor of Chiropractic the correct answer in this context.
