6 transitional epi. structural feature: flexible-including the number of layers and shape of cellls in the distended bladder. there are two to three layers of cells. The cells become flattened n the contracted bladder there are six to seven layers of cells The surface cells are very large and cuboidal in shape covering several deep cells --distribution bladder 表层结胞 深层细胞
