Which of the following best defines "Chiropractic"?

"Chiropractic" is best defined as the science, art, and practice of adjusting the human body's articulations. This definition encapsulates the fundamental focus of chiropractic care, which involves diagnosing and treating mechanical disorders of the musculoskeletal system, particularly the spine, through manual adjustment techniques. Chiropractors believe that proper alignment of the body's structure can aid in overall health and well-being, thus improving the body’s ability to heal itself without the need for invasive procedures or medications.

The emphasis on both the science and art reflects the need for chiropractors to have a solid understanding of anatomy and physiology, as well as the practical skills required for hands-on manipulation. This definition distinguishes chiropractic care from other health practices that might focus on pharmacological treatment or surgical intervention.

In contrast, understanding human physiology is related but does not encompass the specific practice of chiropractic. Herbal medicine refers to alternative treatments that utilize plant-based substances, which is not a primary component of chiropractic practice. Surgical intervention indicates a more invasive approach, which is not consistent with the non-invasive, manual techniques employed by chiropractors. Thus, the chosen definition captures the essence of chiropractic and its holistic approach to health care.
