Ganglion Of Hayfever Flashcards
Where is the pterygopalatine fossa
Beneath apex of orbital cone
Posterior - anterior to pterygoid processor sphenoid bone
Anterior - posterior to maxilla
Lateral - medial to intra temporal fossa
Medial - lateral and posterosup part of superior part of lateral wall so nasal cavity
How does the pterygopalatine fossa communicate with the orbit
Via inferior orbital fissure along with Vb
How does the pterygopalatine fossa communicate with the Middle cranial fossa
Foramen rotundum
Vb before branch
Pterygoid canal
How does the pterygopalatine communicate with the infra temporal fossa and nasal cavity
Infratemporal fossa - pterygomaxillary fissure
Nasal cav - sphenopalatine foramen
Where is the sphenopalatine foramen
In lateral wall of nasal cav between body of sphenoid and perp plate of palatine bone
What does the pterygopalatine fossa contain
Terminal 1/3rd of maxillary artery
Vb
Pterygopalatine ganglion - PARAsymp
What are the branches of the maxillary artery
Superficial temporal Deep auricular Anterior tympanic Meningeal - middle and accessory Inferior alveolar Masseteric Pterygoid Deep temporal Buccal Sphenopalatine Descending palatine Posterior, middle and anterior superior alveolar - infra orbital
Where are the sections of the maxillary artery
Inferior alveolar and masseteric - 1st
Buccal and sphenopalatine - 2nd
After us the 3rd
What is the arterial blood supply to the maxillary teeth
Anterior superior alveolar artery - anteriors
Middle superior alveolar artery - premolars
Posterior superior alveolar artery - molars
What is the somatic sensory of the anterosuprior region of the nasal cav
Anterior ethmoidal branch of nasociliary V1
What is the somatic sensory of the posteroinferior of the nasal cav
Nasopalatine
Greater and lesser
V2
What are the branches of the maxillary division of the trigeminal nerve
Ganglionic branches Posterior superior alveolar Zygomatic which has a communicating to lacrimal gland Zygomaticofacial and zyomaticotemporAl Middle and anterior superior alveolar
What are the parasymp cranial nerves
3- ciliary ganglion - constructor pupillae of the eye
7- pterygopalatine and submandibular - lacrimal nd nasal palatine, salivary sublingual
9- otic ganglion - parotid
10- vagus - ganglia on organs surface
What are the branches of the pterygopalatine ganglion
Nerve of pterygoid canal - greater petrosal nerve parasymp and deep petrosal nerve sympathetic
Lesser palatine nerve - to soft palate
Greater palatine nerve - to had palate
Nasopalatine - to nasal septum
Posterior superior lateral nasal - to mucous mem of lateral wall of nasal cav
Where is the general sensation to for the maxillary division of the trigeminal
Mid face skin Maxillary teeth and gingivae Mucosa of maxillary sinus Walls of nasal cav Hard and soft palate
