Examples: simple squamous epithelium, glandular cuboidal epithelium, transitional epithelium, myoepithelium[CARO]. TAO:0001486 The two basic types of metazoan tissue are epithelial and connective. The simplest metazoans, and developmental stages of many primitive invertebrates, consist solely of these two layers. Thus, epithelial and connective tissues may be the primary (original) tissues of metazoans, and both are important in the functional organization of animals.[well established][VHOG] UBERON:0000483 UMLS:C0014609 VHOG:0000387 XAO:0003045 ZFA:0001486 epithelial epithelial tissue epithelial tissue portion of epithelium portion of epithelium uberon 上皮的 上皮组织 上皮组织 上皮部分 上皮部分 后生动物组织的两种基本类型是上皮和结缔组织。最简单的后生动物和许多原始无脊椎动物的发育阶段仅由这两层组成。因此，上皮和结缔组织可能是后生动物的主要（原始）组织，两者在动物的功能组织中都是重要的。[well established][VHOG] 组织的一部分，由一层或多层上皮细胞通过细胞连接相互连接，并位于一个基底层的下方。例如：简单的鳞状上皮、腺状立方上皮、移行上皮、肌上皮[CARO]。 multilaminar epithelium 多层上皮 unilaminar epithelium 单层上皮 basement membrane of epithelium 上皮基底膜
