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] UMLS:C0014609 VHOG:0000387 XAO:0003045 ZFA:0001486 epithelial tissue epithelium portion of epithelium
