The morphological characteristics of the ileum of 20 adult male Egyptian geese were determined using LM, SEM, and TEM. The mean length of the ileum in the male goose was approximately 158.71 mm, representing nearly 10.19% of the total length of the small intestine. The ileum is composed of four layers: mucosa, submucosa, muscular layer, and serosa. The mucosal layer comprises the epithelium, lamina propria, and muscularis mucosa. The mucosa forms finger-like villi and is invaginated at the bases, forming the crypts of Lieberkühn. The ileum is lined by simple columnar epithelium that contains absorptive dark and light enterocytes with two types of goblet cells (mucous and serous varieties) microfold like cells, dendritic reticulum cells, Paneth cells, and a closed type of enteroendocrine cells. The lamina propria has diffuse lymphoid tissue containing lymphocytes, macrophages, mast cells, plasma cells, and heterophils as well as telocytes. The muscularis mucosa comprises circular smooth muscle fibers extending into the core of the villi. The submucosa is a thin layer of elastic-rich connective tissue. The muscular level consists of four layers, with light and dark smooth muscle fibers. We described in detail the structure of all cellular components and histomorphometric measurements.

鹅（Alopochen egyptiacus）回肠的形态解剖学和组织化学研究，特别涉及免疫细胞、粘液和浆液杯状细胞、端粒细胞以及深色和浅色平滑肌纤维
使用LM、SEM和TEM测定20只成年雄性埃及鹅回肠的形态特征。雄性鹅的回肠平均长度约为 158.71 毫米，占小肠总长度的近 10.19%。回肠由四层组成：粘膜、粘膜下层、肌层和浆膜。粘膜层包括上皮、固有层和粘膜肌层。黏膜形成手指状绒毛并在基部内陷，形成 Lieberkühn 的隐窝。回肠衬有简单的柱状上皮，其中包含吸收性暗和亮肠细胞，以及两种类型的杯状细胞（粘液和浆液性细胞）微褶皱样细胞、树突网状细胞、潘氏细胞和封闭型肠内分泌细胞。固有层具有弥漫性淋巴组织，含有淋巴细胞、巨噬细胞、肥大细胞、浆细胞和嗜异性细胞以及端粒细胞。粘膜肌层包括延伸到绒毛核心的圆形平滑肌纤维。粘膜下层是一层薄薄的富有弹性的结缔组织。肌肉层由四层组成，有浅色和深色平滑肌纤维。我们详细描述了所有细胞成分的结构和组织形态测量。
