Qhov tsis zoo ntawm lub orbital fissure tsim cov ciam teb zoo tshaj ntawm pterygopalatine fossa thiab sib txuas lus nrog lub orbit. Nws yog qhov chaw nruab nrab ntawm cov pob txha sphenoid thiab maxilla. Cov ceg zygomatic ntawm cov hlab ntsha maxillary maxillary hlab ntsha Lub paj hlwb maxillary yog cov ceg thib ob ntawm cov hlab ntsha trigeminal, uas yog keeb kwm embryologically los ntawm thawj lub pharyngeal koov. Nws lub luag haujlwm tseem ceeb yog kev hnov mob rau nruab nrab ntawm peb lub ntsej muag. https://teachmeanatomy.info › taub hau › nerves › maxillary-nerve
Tus Maxillary Division of the Trigeminal Nerve (CNV2)
and the infraorbital artery and vein hla dhau qhov inferior orbital fissure.
Cov ntsiab lus ntawm pterygopalatine fossa yog dab tsi?
Lub pterygopalatine fossa muaj roj thiab cov qauv hauv qab no:
- pterygopalatine ganglion.
- maxillary hlab ntsha (qhov chaw seem), thiab nws cov ceg suav nrog cov hlab ntsha hauv palatine nqis.
- maxillary division ntawm trigeminal hlab ntsha (Vb): nkag los ntawm foramen rotundum.
- ntsej ntawm pterygoid kwj dej.
Dab tsi dhau los ntawm Pterygomaxillary fissure?
Cov ntsiab lus. Lub pterygomaxillary fissure kis lub posterior superior alveolar paj hlwb, ib ceg ntawm maxillary faib ntawm cov hlab ntsha trigeminal los ntawm pterygopalatine fossa mus rau infratemporal fossa. Terminal ceg ntawm cov hlab ntsha maxillary kuj nkag mus rau qhov tawg.
Cov paj hlwb twg nkag mus rau pterygopalatine fossa los ntawm foramen Rotundum?
Cov hlab ntsha maxillary (V2)hla dhau ntawm lub foramen rotundum thiab mus rau hauv cov kwj dej infraorbital, qhov twg, ntawm pterygopalatine fossa, nws ceg mus rau hauv lub pterygopalatine ganglion, nrog parasympathetic thiab sensory. ceg mus rau paranasal sinuses.
Dab tsi cov hlab ntsha taug kev los ntawm infratemporal fossa thiab nkag mus rau pterygopalatine fossa?
Cov hlab ntsha maxillary yog lub xya ceg ntawm sab nraud carotid artery. Nws kawm los ntawm infratemporal fossa ntawm sphenomandibular ligament thiab condylar txheej txheem ntawm mandible nkag mus rau pterygopalatine fossa.
