What is important about the mandibular fossa?
It is an articulation place for the TMJ

What is between the head of the condyle and the mandibular fossa?
Contraction of what muscle pulls both the condylar head and articular disc anterioinferioly to depress the mandible?
What are the muscles of mastication?
What innervates the muscles of mastication?
What portions of the maxillary artery run in the infratemporal fossa?
Where do you find pterygoid plexus of veins?
What part of the maxillary artery do you fine in the pterygopalatine fossa?
What nerve passes through the pterygopalatine fossa?
Maxillary nerve V2
What ganglia do you find in the pterygopalatine fossa?
Where does the Maxillary nerve of the trigeminal nerve enter the pterygopalatine fossa through?
What is the first branch off of the maxillary nerve that is found in the pterygopalatine fossa?
Posterior superior alveolar nerve (PSA)
What is the second branch off of the maxillary nerve found in the pterygopalatine fossa?
What does the zygomatic nerve branch into?
What additional nerve runs with the zygomatic nerve?
-Greater Petrosal nerve (lacrimal gland)
What nerves branch towards the palate in the pterygopalatine fossa?
-Greater palatine nerve
-Lesser palatine nerve
What is a nerve that branches from the greater and lesser palatine nerves and projects anteriorly?
What nerve from the maxillary nerve runs most anteriorly?
What two nerves branch off of the infraorbital nerve?
-Anterior superior alveolar nerve
-Middle superior alveolar nerve
What two nerves are Vidians nerve?
-Greater petrosal nerve
-Deep petrosal nerve
How does Vidians nerve enter the pterygopalatine fossa?
What does the greater petrosal nerve branch off of?
Facial nerve CN VII
How do you find the pterygoid canal?
Go just below the medial pterygoid and posterior and look for a hole
How do you find the palatovaginal canal?
It is usually between the vomer and the medial pterygoid
What runs through the palatovaginal canal?
The pharyngeal branch of the maxillary artery and nerve
What is another name for the palatovaginal canal?
What branch of CN VII leaves from the internal acoustic meatus and goes to the greater petrosal hiatus?
Greater petrosal nerve
What does the lesser petrosal nerve do?
Where does the lesser petrosal nerve leave the skull at?
lesser petrosal hiatus
The greater petrosal nerve enters back through the pterygoid canal
Where does the otic ganglia sit?
What nerve do the major ganglia of the head run with?
What are the four major parasympathetic ganglia found in the head?
What is the sympathetic ganglia found in the head?
Superior cervical ganglion
Sympathetics synapse in the parasympathetic ganglia before going to their target
-They synapse at the superior cervical ganglia but do pass through the parasympathetic ganglia
Is the deep petrosal nerve sympathetic or parasympathetic?
What are all the nerves found in the pterygopalatine fossa?
-Maxillary of V
-Greater petrosal nerve
-deep petrosal nerve

What are all the arteries found in the pterygopalatine fossa?
-Artery of the pterygoid canal
-greater and lesser palatine
-Anterior and middle superior alveolar artery
-Posterior super alveolar artery
Where does the pharyngeal artery pass through?
Palatovaginal canal aka pharyngeal canal
Where does the descending palatine artery leave the pterygopalatine fossa from?
