Test Your Knowledge of Oral Anatomy

• The oral cavity is supplied by multiple arteries from the external carotid artery.
• The lingual artery provides most of the blood supply to the oral tongue and tongue base.
• The artery is located deep to the hyoglossus muscle and can be found by dividing the muscle.
• The hypoglossal nerve and lingual veins are located superficial to the hyoglossus muscle and deep to the mylohyoid muscle.
• The hard palate is supplied by the greater palatine and superior alveolar arteries.
• The greater palatine artery runs anteromedially within the soft tissue of the hard palate.
• The venous drainage from the hard palate is to the pterygoid plexus and subsequently to the internal jugular venous system.
• The superior alveolar arteries provide blood supply to the maxillary gingiva, alveolar ridge, and dentition.
• The ranine vein, which is close to the hypoglossal nerve, can be injured during dissection and must be approached with care.
• Understanding the relationship between the lingual artery, hypoglossal nerve, and lingual veins can aid in localization for microvascular reconstruction or selective ligation.
