The parotid glands lie anterior to the ears between the masseter muscle and the skin. They open into the vestibule next to the second molars of the upper jaw. The submandibular glands lie along the medial aspect of the mandibular body. Their ducts run beneath the mucosa of the oral cavity floor and open at the base of the lingual frenulum. The small sublingual glands lie anterior to the submandibular glands under the tongue. They open via many ducts into the floor of the mouth. Parotid glands contain only serous cells; submandibular glands have equal numbers of serous and mucous cells; and sublingual glands are mostly mucous cells.
