The cells of the deepest layer are columnar; then follow two or three layers of polyhedral cells, the majority of which are prickle cells similar to those found in the stratum mucosum of the cuticle. Lastly, there are three or four layers of squamous cells, with flattened nuclei In zebrafish: nonpigmented, stratified squamous nonkeratinizing epithelial cells, attached to a thick basement membrane that is considered to be analogous to the Bowman's membrane in mammals MA:0001243 MESH:D019573 NCIT:C12928 Portion of tissue comprised of four to six layers of nonkeratinized, stratified squamous cells and represents approximately 60% of the thickness of the cornea.[TAO] TAO:0002187 UBERON:0001772 UMLS:C0459875 ZFA:0001683 anterior corneal epithelium anterior endothelium of cornea cornea epithelial tissue cornea epithelium e. anterius corneae endothelium anterius corneae endothelium camerae anterioris bulbi endothelium corneale epithelial tissue of cornea epithelium anterius (cornea) epithelium anterius corneae epithelium corneæ anterior layer epithelium of cornea epithelium posterius corneae external epithelium of cornea the smooth stratified squamous epithelium that covers the outer surface of the cornea uberon neural crest-derived structure eye epithelium
