Flashcards in Ganglion Of Hayfever Deck (16):

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
Pterygopalatine ganglion - PARAsymp


What are the branches of the maxillary artery

Superficial temporal
Deep auricular
Anterior tympanic
Meningeal - middle and accessory
Inferior alveolar
Deep temporal
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

Greater and lesser


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


What is hay fever

Sneezing stuffy runny nose
Watery eyes
Allergy to pollen
Acute inflammation of nasal mucosa dilated blood vessels
Activation of ganglion of hay fever
Naval glands secrete mucus
Lacrimal gland produces tears
