Study Notes
- The floor of the mouth is formed by the mylohyoid, geniohyoid, and genioglossus muscles.
- The Greek/Latin term for lips is labra.
- A horizontal line sometimes present on the buccal mucosa is the linea alba.
- The parotid duct opens opposite the upper 7's.
- The buccinator and superior pharyngeal constrictor muscles insert into the pterygomandibular raphe.
- During an I03 block, the buccal, incisive, lingual, and mental nerves are anesthetized.
- During a SANB is an anterior, middle, posterior, nasopalatine, and greater palatine nerve block.
- The space around the teeth and alveolar process is the vestibule.
- The palatal roots of teeth 4 and 5, and the mesiobuccal root of tooth 6 are close to the maxillary sinus.
- The auriculotemporal nerve (posteriorly) and the masseteric nerve (anteriorly) provides sensory innervation to the TMJ capsule.
- The pterygomandibular raphe ligament connects directly to the pterygoid hamulus.
- The body of the maxillary bone (central body) houses roots and sinuses
- The processes of the maxillary bone include the zygomatic, frontal, palatine (anterior portion articulates with palatine bones), and alveolar processes.
- The infraorbital foramen is a feature of the maxilla
- The canine fossa is for the Caninus/Levator anguli oris
- The tuberosity the posterior part, bony prominence, and muscle attachment of the maxilla.
