Abstract：
BACKGROUND: Publications report that all mammals have two omenta, namely, lesser omentum and greater omentum. Basically, these organs, which share the same name except for the adjective \"lesser\" or \"greater,\" should not differ from each other. However, no clear description of the structure of the lesser omentum, as well as comparative morphological analysis between the lesser and greater omenta have been found in the literature, which necessitates a thorough investigation. Therefore, the aim of our study was to analyze the morphofunctional differences between the greater and lesser omenta in albino rats.
METHODS: The experiment involved 20 mature male albino rats, weighing 298,28±7,36 grams. The material for our study were preparations of lesser and greater omenta, fixed in 10 % of neutral buffered formalin. Paraffin sections were stained with hematoxylin-eosin and Van Gieson stain.
RESULTS: The findings of the study showed that the greater omentum in albino rats, unlike other derivatives of the omentum (ligaments and mesenteries), represents a free extension (mostly from the greater curvature of the stomach), in the form of an \"apron,\" into a specific depth of the peritoneal cavity, duplicating the serous membrane. This duplication is characterized by the composition of two structurally interdependent formations. These include vascular-fatty arcades, associated with lymphoid nodules known as milky spots, and binding serous-reticular membranes. The findings of the study of the lesser omentum have established that in all cases it is located beneath the liver and becomes visualized only after hepatolifting. It is presented in the form of two ligaments: hepatoduodenal and hepatogastric, which contain two main structured formations, which we called vascular-fatty spurs, between these spurs, serous-reticular membranes are located.
CONCLUSIONS: despite having similar names, the lesser omentum, a derivative of the peritoneum, is fundamentally different. As it is well known, the lesser omentum is represented by ligaments that extend from the liver hilus to the lesser curvature of the stomach and the duodenum. Due to this arrangement, the lesser omentum lacks the mobile activity characteristic of the greater omentum, which plays a crucial role in rapid response to damage in the gastrointestinal tract. Despite sharing the same names, both formations differ in shape, morphological structure, development and function.

摘要：
背景：出版物报道所有哺乳动物都有两个小网膜，即,小网膜和大网膜。基本上,这些器官,除了形容词“更小”或“更大”之外，它们共享相同的名称，“不应该彼此不同。然而,小网膜的结构没有明确的描述，以及在文献中发现的较小和较大的网膜之间的比较形态学分析，这就需要进行彻底的调查。因此,我们研究的目的是分析白化病大鼠大网膜和小网膜之间的形态功能差异。
方法：本实验采用20只成年雄性白化病大鼠，重298,28±7,36克。我们研究的材料是较小和较大的网膜的制剂，固定在10%的中性缓冲福尔马林中。石蜡切片用苏木精-伊红和VanGieson染色。
结果：研究结果表明，白化病大鼠的大网膜，与网膜的其他衍生物（韧带和肠系膜）不同，表示自由延伸（主要来自胃的较大曲率），以“围裙”的形式，“进入腹膜腔的特定深度，复制浆膜。这种重复的特征在于两个结构上相互依赖的形式的组成。这些包括血管脂肪拱廊，与称为乳状斑点的淋巴结节有关，和结合浆液网状膜。小网膜的研究结果已经确定，在所有情况下，它都位于肝脏下方，只有在肝剥离后才能可视化。它以两种韧带的形式出现：肝十二指肠和肝胃，其中包含两个主要的结构化地层，我们称之为血管脂肪刺，在这些马刺之间，浆液网状膜位于。
结论：尽管名称相似，小网膜，腹膜的衍生物，根本不同。众所周知,小网膜由从肝门延伸到胃和十二指肠的小曲率的韧带代表。由于这种安排,小网膜缺乏大网膜的移动活动特征，在对胃肠道损伤的快速反应中起着至关重要的作用。尽管有相同的名字,两种地层的形状不同，形态结构，发展和功能。
