Infratemporal Fossa and Oral Cavity Flashcards
Which nerve must be anesthetized to drain an abscess affecting the cheek area?
Buccal (V3)
The buccal nerve is responsible for carrying pain sensations from the cheek area.
Which nerve should be anesthetized to work on a mandibular molar tooth affected by dental caries?
Inferior alveolar
The inferior alveolar nerve innervates the mandibular teeth.
Which nerve is endangered during the surgical removal of an impacted third mandibular molar tooth?
Inferior alveolar n.
The inferior alveolar nerve is closely associated with the lower third molar.
Damage to the lingual nerve before it joins the chorda tympani causes loss of what?
General sensation to the anterior two thirds of the tongue
A cranial fracture through the foramen ovale compresses which nerve affecting all muscles except one?
Buccinator
The buccinator muscle is not affected by the nerve compressed in this scenario.
What is the position of the condyles of the mandible in bilateral anterior dislocation of the jaw?
Against the anterior slope of the articular eminence
At the temporomandibular joint (TMJ), hinge movements occur between which two structures?
Condyle and articular disc
Incapacity to protrude the mandible indicates dysfunction of which muscle?
Lateral pterygoid
What muscle mainly accomplishes the forward movement of the condyle during wide opening of the jaws?
Lateral pterygoid muscle
Excessive contraction of which muscle causes displacement of the articular disc in jaw dislocation?
Lateral pterygoid
Which suprahyoid muscle would be paralyzed if the inferior alveolar nerve were severed at its origin?
Mylohyoid m.
Paralysis of which muscle would impede retraction of the mandible?
Temporalis
Which muscle is responsible for raising the floor of the mouth in the early stages of swallowing?
Mylohyoid
What artery was involved in an accident during the surgical reduction of TMJ ankylosis?
Maxillary
Which vessel needs to be protected when accessing the submandibular gland?
Facial artery
