Respiratory motion of cranial bones- Does mouth breathing disrupt this?
Thursday, July 5, 2012 at 12:09PM The cranial bones are proposed to move in synchrony with inspiration and expiration. Its quite beautiful to watch this 3-D animation of the occiput, sphenoid and ethmoid doing their co-ordinated respiration dance with the ethmoid rising to invite the inspiration and the sphenoid widening to broaden the maxilla. A question that comes to mind is how much does chronic mouth breathing interfer with this? How do structure and function interact?
