• Tall prismatic cells, oval nucleus, tight contact to the basal lamina, up to 300 microvilli on the apical surface: Simple columnar resorptive epithelium.
• Globular complexes with central small lumen, made of cells with pyramidal shape and pronounced apical acidophilia and basal basophilia: Serous secretory epithelium.
• Elongated eosinophilic structural syncytia with clearly pronounced regular transverse striations and round peripherally located nuclei: Transversely striated skeletal muscle tissue.
• Weakly contacting fixed and migrating cells with diverse morphological characteristics and abundance of extracellular matrix rich in diverse fine fibers: Loose connective tissue.
• Complexes of polyhedral cells in close contact with each other within scarce extracellular matrix without visible ducts or cavities: Endocrine glandular epithelium.
