Which statement accurately describes the relationship between primary respiratory mechanism and secondary respiratory influences in cranial theory?

• A. Primary respiratory mechanism is the inherent cranial motion; secondary respiration arises from autonomic or biomechanical influences
• B. Primary respiratory mechanism is the same as secondary respiration
• C. Secondary respiration is voluntary
• D. There is no such thing as secondary respiration

Answer: (A)

The key idea is that cranial theory distinguishes an intrinsic rhythm of the cranial system from external influences that can modify it. The primary respiratory mechanism is the inherent cranial motion generated by internal forces such as cerebrospinal fluid pulsations and the tissue dynamics of the brain and membranes. Secondary respiration refers to additional, respiration-like changes that come from autonomic nervous system input or biomechanical influences like tissue tension, sutural restrictions, or external manipulation. So the correct description is that the primary respiratory mechanism is the inherent cranial motion, while secondary respiration arises from autonomic or biomechanical influences. It’s not the same as secondary respiration, it’s not voluntary, and there is such a thing as secondary respiration.
