maxillary nerve การใช้

• These are all branches of maxillary nerve.
• Both the lesser palatine and the zygomatic are maxillary nerves ( from the trigeminal nerve ).
• The superior alveolar ( anterior, middle, and posterior ) nerves, branches of the maxillary nerve provide sensory innervation.
• The lacrimal nerve is occasionally absent, and its place is then taken by the zygomaticotemporal branch of the maxillary nerve.
• The maxillary nerve, division V 2 of the trigeminal nerve travels through the lower portion of the sinus and exits via the foramen rotundum.
• Although it is closely related to the pterygopalatine ganglion, it is still considered a branch of the maxillary nerve and does not synapse in the ganglion.
• Sensory innervation of the whiskers is provided by the infraorbital branch of the trigeminal maxillary nerve; motor innervation is attributable to the facial ( VII ) nerve.
• In the orbit it runs along the upper border of the lateral rectus, with the lacrimal artery, and communicates with the zygomatic branch of the maxillary nerve.
• A small quantity of fat, the orbital branch of the superficial temporal artery, and a filament from the zygomatic branch of the maxillary nerve, are contained between these two layers.
• It also sends postganglionic parasympathetic fibers to the lacrimal nerve ( a branch of the Ophthalmic nerve, also part of the trigeminal nerve ) via the zygomatic nerve, a branch of the maxillary nerve ( from the trigeminal nerve ), which then arrives at the lacrimal gland.
• Cavernous sinus syndrome may result from mass effect of these tumors and cause ophthalmoplegia ( from compression of the oculomotor nerve, trochlear nerve, and abducens nerve ), ophthalmic sensory loss ( from compression of the ophthalmic nerve ), and maxillary sensory loss ( from compression of the maxillary nerve ).
