|
|
The Maxillary N passes through the ______to enter the PtP fossa, then enters the orbit as the ____ and terninates by passing through the ____.
|
foramen rotundum
infraorbital N infraorbital foramen |
|
|
What are the 3 branches of V2 while in the pterygopalatine fossa?
|
pterygopalatine
zygomatic posterior superior alveolar |
|
|
________that connect to the PtP ganglion . Sensory fibers of the V2 pass through the branches of the ganglion to supply the nasal cavity, the hard and soft palate, and the pharynx
|
Pterygopalatine nerves
|
|
|
Zygomatic N. enters the orbit through the inferior orbital fissure and divides into the _____(skin of face), and _____(skin of face).
|
Zygomaticotemporal N
zygomaticofacial N |
|
|
________ N descends on the tuberosity of the maxilla, enters the _____foramen to supply the maxillary sinus and the last three molars
|
posterior superior alveolar
|
|
|
______ also contains postganglionic parasympathetic and sympathetic from the PtP ganglion. These fibers follow the ______and then via the communicating branch to the _____, the autonomic fibers get to the lacrimal gland
|
zygomatic N
zygomaticotemporal N lacrimal N |
|
|
The V2 N enters the orbit through the inferior orbital fissure, lies in the infraorbital groove as the_______and gives off the_____and the ________to supply the sinus, 2 upper bicuspid and incisor teeth and gingivae.
|
infraorbital N
middle and anterior superior alveolar NN |
|
|
The Infraorbirtal N leaves the orbit passing through the infraorbital foramen and gives off the 3 terminal branches: 1. _______to skin and conjunctiva of lower eyelid. 2.______to skin of lateral nose. 3._____ to skin and mucous membrane of upper lip.
|
1. inferior palpebral brs
2. external nasal brs 3. superior labial brs |
|
|
Describe the VE pathway from the brainstem and internal carotid artery
|
Preganglionic parasympathetic fibers from cell bodies in the brain stem follow the facial N, pass through the geniculate ganglioin, and leave the petrous part of the temporal bone as the greater petrosal N. as these fibers reach the foramen lacerum, the postganglionic sympathetic fibers from the internal carotid A join the greater petrosal N as the deep petrrosal N. Both NN enter the pterygoid canal as the N.of the pterygoid canal. The pterygoid canal opens into the pterygopalatine PtP fossa, where the preganglionic parasympathetic fibers synapse. These autonomic fibers then join the brs of the PtP ganglion and supply the mucosa of the nasal cavity, the pharynx the hard and soft palate, and via the brs of the Zygomatic N to the lacrimal gland
