    A: Circumvallate papillae

    B: Taste buds stain lighter than the epithelium that surrounds them

    C: Von Ebner's gland is a compound multicellular alveolar exocrine gland that secretes lingual lipase.

    A: Taste buds are located within the epithelium and are unipolar neurons histologically.

    B: Stratified squamous epithelium

    A: Stratified squamous epithelium

    B: Taste buds are made of sustentacular cells which lend structural support, and unipolar neurons that receive gustatory stimulation. These cells are elongated and have a light staining cytoplasm.

    C: Taste pore is an opening at the surface of the epithelium

    Olfactory 40X
    A: Olfactory epithelium is ciliated pseudostratified columnar epithelium and it also houses the olfactory cells which are bipolar neurons

    B: Bowman's glands are simple multicellular branched tubular exocrine glands

    C: Ducts of the Bowman's gland

    Olfactory Cells
    A: Bipolar neurons are difficult to see because they are embedded within the respiratory epithelium and extend from the basement membrane to the exterior.

    B: Cilia located on the apical surface of the epithelium
