• It is the procedure for dentist to
anesthesize nerve supply of lower
teeth and gum before dental

ramus and medial pterygoid m.)
• Nerves block:1.Inferior alveolar
n.,2.Lingual n. and 3.buccal n.
54. 5. The maxillary
nerve (V2)It is pure sensory nerve and divided into
three ramus as follows:
1.External ramus(Zygomatic n.):They are
zygomaticofacial and zygomaticotemporal
nerves
2.Intermediate ramus:It is infraorbital nerve
which gives off branches.
2.1.Posterior,middle and superior alveolar
nerves which supply alveolar and upper teeth
2.2.Infraorbital nerve which traverses
infraorbital foramen to supply cheek and
lower eyelid.
55. 5.Maxillary nerve (V2)(continue)
• 3.Internal ramus(pterygopalatine or
sphenopalatine n.):It supplies nasal
cavity and palate.The branches are
following.
• 3.1.Sphenopalatine nerve:It
enters the
• sphenopalatine foramen to supply
nasal cavity.Its
• terminal branch is incisor nerve
which supplies upper incisor.
• 3.2.Descending palatine
nerve:After descendent,this nerve
ramified to be these
• branches.
• 3.2.1.Greater palatine
n.which supplies hard palate.
56. 5.Maxillary
nerve(V2)(continue)• Moreover,pterygopalatine ganglion
situated medial to rostral internal
ramus(pterygopalatine n.).The greater
petrosal n.(preganlionic fiber) of CN.VII
(facial n.) came to synapse with this
ganglion.The postganglionic fibers merged
• with internal ramus branches to supply
seromucous gland in palate and nasal
cavity.
• There was some postganglionic fiber
• running with zygomaticotemporal n. to
meet the lacrimal n.(sensory)of V1.It came
along with this nerve to supply lacrimal
gland for gland secretion.
