[Helping factors of the occlusion and oppening mechanisms of gastric cardiac region in opossum. Comparative study to the man (author's transl)].
The morphological factors that should work to help the cardial occlusion (esophageal and gastric mucosal folds) and are arranged to cooperate for the cardial oppening (smooth muscle fibres of the longitudinal layer of esophagus and stomach) are described in opossum (Didelphis albiventris), comparatively to the man. Also are comparatively discussed the anatomical disposition of diaphragm, esophageal hiatus of diaphragm, gastrophrenic ligament and phrenosophagical membrane.
