Vasculature • Lingual artery from external carotid • Lingual vein Glands • Submandibular gland • Sublingual gland Nerves • Lingual nerve • Hypoglossal nerve • What nerve supplies general sensory to the anterior 2/3 of the tongue? o CN V3 • What nerve supplies special sensory to the anterior 2/3 of the tongue? o Chorda tympani, CN VII • What nerve supplies general sensory to the posterior 1/3 of the tongue? o Glossopharyngeal • What nerve supplies special sensory to the posterior 1/3 of the tongue? o Glossopharyngeal • What nerve supplies the epiglottis and epiglottal region of the tongue? o CN X, Superior laryngeal nerve • Muscles of Complete the following: Enamel Ameloblasts Dentin Dentinoblasts  Cementum Cementoblasts Which nerves supply the Maxillary  V2, superior alveolar nerve teeth? Mandibular  V3, inferior alveolar nerve How do you block… Superior alveolar Infraorbital, but could affect orbicularis oculi Pterygomaxillary fissure, but could enter pterygoid plexus and cause widespread hematoma Nasopalatine block for primary palate, but can pierce blood vessels and very painful How do you block… Mouth of mandibular canal, injections site at thumbs width behind 3rd molar. Inferior alveolar Hazards include damage to the inferior alveolar artery, facial nerve and loss of orbicularis oris How do you block… Anesthetized with inferior alveolar nerve Lingual nerve? How do you block… Mental foramen (must check?). Hazard is hurting the mental artery. Mental Nerve? What is the blood supply Maxillary – Anterior, middle, and posterior alveolar. Anterior and middle are to the teeth? from infraorbital artery (branch of maxillary) and posterior is from maxillary artery.

Mandibular is from inferior alveolar artery as a branch from the maxillary
