本文描述了28种中型蜥蜴和44种中型蜥蜴的肺，代表了7个中型蜥蜴科中的6个科的中型蜥蜴和该分类群所有7个科的肺。在cordylids，gerrhosaurids，xantusiids和lacertids的完整的右腹mesoppronium（VMp）插入颅侧的后腔静脉和尾侧的背表面上的右肝叶。在心形类和撕裂类中，左VMp附着于腹外侧体壁;在gerrbosaurids中，左VMp较短，插入心包和后腔静脉;在xantusiids中，左VMp减少，肺与心包颅侧融合。在正常情况下，两侧VMp长度不等，插入腹系膜上，或完全缺失。裸眼动物Calyptommatus和Noorachia的内脏拓扑结构与一般的裸眼动物不同，肝脏和胃被拉长，分别位于体腔的右侧和左侧。左和右VMp在肺的整个长度上延伸并插入腹侧肠系膜上。在这项研究中检查的所有肺都是单腔的，除了蜥蜴、一些gerrhosaurids、Cordylus和两个裸眼龙属（棘龙属和Neusticurus）外，没有显示出内表面的主要结构变异。在这些组中，存在成排的背内侧壁龛。© 2005 Elsevier GmbH。All rights reserved.
Mesopneumonia of 28 and lungs of 44 species of scincomorph lizards are described, representing mesopneumonia in six of the seven scincomorph families and lungs of all seven families of this taxon. Except for gymnophthalmids and scincids, a family typical organization of mesopneumonia occurs. In cordylids, gerrhosaurids, xantusiids and lacertids the complete right ventral mesopneumonium (VMp) inserts cranially on the posterior vena cava and caudally on the dorsal surface of the right liver lobe. The left VMp is attached to the ventrolateral body wall in cordylids and lacertids; in gerrbosaurids the left VMp is short and inserts on the pericardium and the posterior vena cava; in xantusiids the left VMp is reduced and the lungs are fused cranially with the pericardium. In scincids the VMp of both sides vary in length and insert on the ventral mesentery, or may be lacking completely. The visceral topology of the gymnophthalmids Calyptommatus and Notobachia differs from the general scincomorph pattern, with the liver and stomach elongated and situated on the right and left side of the body cavity, respectively. The left and the right VMp extend over the entire length of the lungs and insert on the ventral mesentery. All lungs examined in the study are single-chambered and show no major structural variability of the inner surfaces, except in lacertids, some gerrhosaurids, Cordylus, and two genera of gymnophthalmids (Echinosaura and Neusticurus). In these groups, rows of dorsomedial niches are present. © 2005 Elsevier GmbH. All rights reserved.
