Which principle states that Structure and Function are reciprocally interrelated?

Which principle states that Structure and Function are reciprocally interrelated?

• A. The body is a unit (mind, body, spirit)
• B. Structure and Function are reciprocally interrelated
• C. Rational treatment is based upon understanding of the first 3 principles
• D. The body is capable of self-regulation, self-healing and health maintenance

Answer: (B)

Structure and function influence each other. This principle holds that how the body is built affects how it works, and how it works, in turn, shapes its structure. In practice, abnormalities in structure—like restricted joint motion or misalignment—can disrupt circulation, nerve function, and overall physiology. Conversely, chronic functional issues can drive adaptive changes in bones, muscles, and connective tissue, altering structure over time. This reciprocal relationship is central to osteopathic thinking and guides treatments that aim to restore normal structure to improve function, and as function improves, structure can rebalance as well. The other statements describe related ideas—the body as a unit, self-regulation and healing, or a basis for rational treatment—but they do not express the explicit bidirectional link between structure and function.
