  • Front
  • Back
Innervation of maxillary teeth
Posterior superior alveolar nerve (branch of V2), the middle superior alveolar nerve (branch of infraorbital nerve, V2), and the anterior superior alveolar nerve (branch of infraorbital nerve (V2).
Innervation of mandibular teeth
Inferior alveolar nerve (branch of mandibular nerve, V3).
Hard Palate bones
Palatine process of the maxilla and horizontal plate of the palatine bone.
Greater palatine foramen
Large opening created by the edge of the maxilla and the edge of the palatine bone.

Greater palatine vessels and nerves use to enter and leave the hard palate.
Lesser palatine foramen
In the substance of the palatine bone.

Transmits the lesser palatine neurovascular structures.
Incisive canal/foramen
Nasopalatine nerve exits to pass posteriorly and connect with the greater palatine nerve coming anteriorly.
Mylohyoid muscle
Mandible to hyoid bone.

situated immediately above the anterior belly of the digastric muscle. Forms a muscular floor for the cavity of the mouth.

Innervated by the mylohyoid nerve, from the mandibular division of the trigeminal nerve (V3).
Geniohyoid muscle
Superior to the mylohyoid. Runs from the hyoid to the back of the mandible. Floor of mouth.
Genioglossus muscle
Extrinsic tongue muscle.

Attachment on the mandible on the superior genial spine.
Hypoglossus muscle
Extrinsic tongue muscle.

Hyoid to lateral parts of tongue.

Depresses, retrudes tongue.
Lingular Nerve
Branch from V3 (mandibular).

Anterior to inferior alveolar nerve. Travels first lateral and then medial to the submandibular duct.

Afferent fibers from the anterior 2/3 of the tongue for “touch".

Also efferent fibers from the facial nerve that branch off from the facial nerve in the chorda tympani nerve and then enter the lingual nerve. These fibers then synapse in the submandibular ganglion; postganglionic fibers then travel to the submandibular and sublingual glands causing them to salivate.
Submandibular ganglion
Rests on the lateral surface of the hyoglossus muscle.
Innervation is via the superior labial nerve (branch of infraorbital nerve V2) and inferior labial nerve (branch of mental nerve V3)
Submandibular and sublingual salivary glands innervation
Parasympathetic innervation from the facial nerve (via chorda tympani branch/lingual nerve and its synapse on the submandibular ganglion).
Parotid gland innervation
Receives its parasympathetic innervation from the glossopharyngeal nerve (CN IX) (via otic ganglion).
What nerve crosses under the submandibular duct twice?
The lingual from V3.
Levator veli palatini
Pharyngotympanic tube and petrous part of temporal bone to palatine aponeurosis.

Pharyngeal branch of CN X via pharyngeal plexus.

Elevates soft palate during swallowing and yawning.

Elevates soft palate during swallowing and yawning.
Tensor veli palatini
Medial pterygoid plate, sphenoid bone and cartilage of pharyngotympanic tube to Paltine aponeurosis.

Wraps around hook of Hamulus.

Nerve to medial pterygoid (V3) via otic ganglion.

Tenses soft palate and opens mouth of pharyngotympanic tube during swallowing and yawning.
Sensory innervation to hard and soft palate
Greater and lesser palatine nerves via greater and lesser palatine foramina. Both come from V3 through pterygopalatine ganglion. Also nasopalatine nerve same path.
