This volume represents edited material that was presented at a conference on brainstem modulation of spinal nociception held in Beaune, France during July, 1987. covers the thoracic wall and superior face of the diaphragm, covers the external lung surface, dipping into lining its fissues, pressure exerted by the air surrounding the body, difference between intrapulmonary and intrapleural pressure, relationship between pressure and volume of a gas, the diaphragm and external intercostal muscles, occurs whenever we cough, sneeze, cry, laugh, hiccup, yawn, - airway diameters in the first part of the conducting zone are huge, relative to the low viscosity of air, the unequal attraction produces a state of tension at the liquid surface. On the right side, the dorsal respiratory group (DRG) is located within the solitary nucleus, and the ventral respiratory group (VRG) is ventral to the nucleus ambiguus. In the pons, the pontine respiratory group is made up of two areas – the pneumotaxic centre and the apneustic centre. Pneumotaxic center C) alveolar type II cells start secreting pulmonary surfactant around week 28. In the medulla they are the dorsal respiratory group, and the ventral respiratory group. The respiratory center is made up of three major respiratory groups of neurons, two in the medulla and one in the pons. two types of mucous membranes in nasal cavity?
