Submandibular Gland Anatomy
• within the submandibular triangle (inferior to mylohyoid muscle, superior to the digastrics)
• superficial layer of the deep cervical fascia envelops the gland and contains the marginal mandibular nerve
• hypoglossal nerve runs deep to the digastric tendon and medial to the deep layer of the deep cervical fascia
• facial artery arises from the external carotid artery and courses medial to the posterior digastric muscle then hooks over the muscle to enter the gland and exits into the facial notch of the inferior mandible
• lingual artery runs along the lateral aspect of the middle constrictors, deep to the digastrics, and anteriorly and medially to the hyoglossus
• Histological Cell Type: mixed cells (serous and mucinous)
• Wharton’s Duct: opens lateral to frenulum in the anterior portion of the floor of mouth, behind the incisors
