Various Human Salivary Glands

Description

Parotid, submandibular, and sublingual salivary glands occupy the lateral face and floor of mouth in a single oral-region field. The parotid gland sits anteroinferior to the external acoustic meatus, draping over the masseter and approaching the mandibular ramus, while the submandibular gland lies inferior and medial to the mandibular body within the submandibular triangle. Along the anterior floor of the mouth, the sublingual glands form elongated lobulated pads superior to the mylohyoid and lateral to the genioglossus, positioned adjacent to the lingual surface of the mandible. Major excretory pathways are typically readable by their anatomic course, with the parotid (Stensen) duct crossing the masseter and turning medially toward the buccal vestibule, and the submandibular (Wharton) duct tracking forward toward the sublingual caruncle. Duct anatomy matters. Obstruction of the submandibular duct by sialolithiasis classically produces postprandial pain and swelling in the submandibular region, and the illustration helps you relate the gland to the mylohyoid sling and the midline structures of the floor of mouth that influence stone location and surgical access. Parotid pathology, including bacterial parotitis and pleomorphic adenoma, is often discussed alongside the course of the facial nerve within the gland, so a lateral facial placement of the parotid provides a practical scaffold for teaching nerve-sparing parotidectomy concepts. Dental anatomy courses and head and neck blocks use this illustration to anchor oral cavity gland topography, duct orifices, and referred symptoms in xerostomia from Sjogren syndrome or medication effects. Medical publishers can pair it with clinical text on sialadenitis, ranula formation from sublingual gland mucus extravasation, and ultrasound or sialography correlations that depend on knowing where each gland sits.
