In domestic animals, the buccal glands are regarded as small versions of salivary glands scattered in the oral cavity. This study oultines how two kinds of buccal glands can be detected and shows where they are located in the head of the Philippine carabao. It also gives measurements of the sizes of these glands. The middle buccal gland reportedly present in most species of domestic animals was absent in the carabao, as noted. Using different histochemical strains, the presence of neutral, sulfated and acidic mucosubstances in the mucous secretory units was demonstrated in the upper buccal gland but not in the lower gland of the Philippine carabao. Although mixed glands, the buccal glands were shown to be predominantly mucous. Their secretions, together with those of other major salivary glands, coat the food for easier passage from the oral cavity to the esophagus and protect the mucosa of the pharynx and esophagus from mechanical injury
