innervates maxillary sinus
posterior superior alveolar 2
sensory innervation to mucosa of the hard palate
greater palatine 2
true or false
anterior superior alveolar supplies MB root of max 1st molar
false, middle superior alveolar 2
which nerve supplies soft palate
lesser palatine 2
infraorbital gives off into which two branches
anterior superior alveolar
middle superior alveolar 2
What nerve travels through the incisive foramen to innervate the lingual gingiva of the maxillary central incisors?
nasopalatine 2
Which of the following is NOT innervated by the posterior superior alveolar nerve?
A. Maxillary molars (except MB root of 1st molar)
B. Maxillary sinus
C. Maxillary buccal gingiva
D. Maxillary central incisors
D. Maxillary central incisors 2
Which nerve supplies the buccal gingiva of the maxillary molars?
Posterior Superior Alveolar 2
- Match the nerve with the structure it innervates:
Nerve
A. Nasopalatine
B. Posterior Superior Alveolar
C. Greater Palatine
Structure Innervated
1. Buccal gingiva
2. Lingual gingiva of maxillary incisors
3. Mucosa of hard palate

C3
Which nerve is primarily responsible for sensory innervation to the anterior maxillary teeth?
Anterior Superior Alveolar N. 2
Which of the following does NOT pass through the pterygopalatine fossa?
A. Posterior Superior Alveolar N.
B. Nasopalatine N.
C. Greater Palatine N.
D. Mandibular Nerve (V₃)
D. Mandibular Nerve (V₃)
V₃ goes through the foramen ovale, not the pterygopalatine fossa. Only V₂ branches are found there.
This nerve exits through the foramen rotundum and enters the pterygopalatine fossa
Pterygopalatine 2
This nerve descends through the greater palatine canal and splits into two branches
Descending palatine 2
Supplies mucosa of the hard palate
Greater Palatine Nerve 2
Enters nasal cavity and travels through incisive foramen
Nasopalatine 2
Supplies posterior maxillary molars and sinus
Posterior Superior Alveolar 2
Gives rise to anterior and middle superior alveolar nerves
Infraorbital 2
Supplies anterior maxillary teeth
Anterior Superior Alveolar 2
Supplies MB root of 1st molar and premolars
Middle Superior Alveolar 2
The nasopalatine nerve exits the skull through the infraorbital foramen.
False, it exits through the incisive foramen 2
Which of the following nerves does NOT arise from the infraorbital nerve?
A. Anterior Superior Alveolar N.
B. Middle Superior Alveolar N.
C. Posterior Superior Alveolar N.
D. Palpebral branches
C. Posterior Superior Alveolar N.
The PSA nerve branches directly off V₂ before it becomes the infraorbital nerve. The palpebral branches (to the lower eyelid) do come from the infraorbital nerve after it exits the infraorbital foramen. 2
Which of the following is NOT a function of any branch of the maxillary nerve (V₂)?
A. Sensation to the soft palate
B. Sensation to the lower teeth
C. Sensation to the nasal cavity
D. Sensation to the maxillary sinus
B. Sensation to the lower teeth
The mandibular nerve (V₃) provides sensation to the lower teeth via the inferior alveolar nerve, not V₂.
