The diaphragm is the major muscle that controls breathing. Is this muscle voluntary or involuntary?
  1. Voluntary
  2. Involuntary
  3. Both
  4. Neither
Explanation
Answer: C - The diaphragm is voluntary and involuntary. It is involuntary because you do not have to consciously think about taking a breath every time you inhale or exhale. This is illustrated when you hiccup involuntarily. It is also voluntary because you can change the way you breathe, for instance when you hold your breath.
