Minor Salivary Glands
There are hundreds of minor salivary glands throughout the mouth and the aerodigestive tract. Unlike the major salivary glands, these glands are besides belittled to be seen without a microscope. Most are found in the lining of the lips, the natural language, and the roof of the mouth, equally well as inside the cheek, nose, sinuses, and larynx ( articulation corner ) .
