Tempora, infratemporal region

Question 1

what vv goes through the parotid gland

Answer 1

superficial temporal

Question 2

retroman vv formed from

Answer 2

junction of the superficial temporal and maxillary vv

Question 3

interesting feature of the vv of the angular region

Answer 3

possess no valves, can drain to cavernous sinus

Question 4

what splits the parotid into superficial and deep?

Answer 4

CN VII

Question 5

what vv is in the parotid gland?

Answer 5

retroman vv

Question 6

ciliary ganglion
location
fibers from?
targets?

Answer 6

in the orbit
parasym from CN 3 (pregang fibers)
sym from the superior cervical plexus (postgang fibers)
targets the sphincter papillae and lens for accomodation

Question 7

pterygopalatine ganglion
location
fibers from?
targets?

Answer 7

located in pterygopalatine fossa
parasym from greater petrosal nn of CN 7 (pregang)
sym from superior cervical plexus (postgang)
targets lacrimal and nasal glands

Question 8

otic ganglion
location
fibers from?
targets?

Answer 8

between tensor palatini veli and the mandibular nn
parasym fibers from tympanic nn of CN 9 (pregang)
sym from the superior cervical plexus
targets the parotid gland

Question 9

submandibular ganglion
location
fibers from?
targets?

Answer 9

located on surface of hyoglossus mm
parasym from chroda tympani of CN 7 (pregang)
sym from superior cervical plexus
targets the subman and sublingual gland

Question 10

anterior to the ext auditory meatus?

Answer 10

mandibular condyle

Question 11

Ear pain can often be from what dental pathology? inn of area

Answer 11

TMJ, but TMJ pain could be associated with ear abnormality

inn of the area is very complex: CN’s 5,7,9, and 10 all present

Question 12

ligaments of TMJ

Answer 12

fibrous capsule
lat ligament
stylomandibular ligament
sphenomandibular ligament

Question 13

TMJ opening

Answer 13

two parts
initally just simple hinge and rotation within the mandibular fossa
further opening results in anterior movement of the condyle/articular disc

Question 14

sensation of TMJ

Answer 14

lots from CN V but other nn contribute too

Question 15

articular disc of TMJ

Answer 15

divides the sup/inf portions of the joint capsule

Question 16

pathway of CN 9 contribution to otic ganglion

Answer 16

will send preganglionic parasym to typnaic plexus in the tympanic cavity (tympanic nn)
then projects as lesser petrosal nn to the otic ganglion for synapse

Question 17

importance of the lingula

Answer 17

mandibular foramen on other side of it>where the inf alveolar nn will enter
lingual nn also moves alongside it
sphenomandibular ligament attatches here

Question 18

nn of the man condyle

Answer 18

all from CN V3 
deep temporal
auriculotemporal 
masserteric 
lots of inn means lots of pain with any inflammation

Question 19

aa lateral to the TMJ

Answer 19

superficial temporal Aa

Question 20

eutaschian/ pharyngotympanic tube

Answer 20

allows ears to adjust to pressure changes

tube from the nasal cavity to the ears

Question 21

movements of the mandible

Answer 21

protrusiuon 
retraction
elevation 
depression 
rotation

Question 22

mm that form a sling for the mandible

Answer 22

massetter and medial pterygoid

Question 23

mm for mandible elevation

Answer 23

temporalis
massetter
med pterygoid

Question 24

mm for mandible depression

Answer 24

lat pterygoid (pulls forward/down) 
suprahyoid/infrahyoid mm

Question 25

protrusion mm for mandible

Answer 25

lat pterygoid
massetter
med pterygoid

Question 26

mm of mandbile retrusion

Answer 26

temporalis (posterior/middle portions)

massester

Question 27

mm for mandbile lateral movement

Answer 27

same side temporailis

oppsosite side pterygoids and massetter

Question 28

suprahyoid mm

Answer 28

digastric ant/ post belly
stylohyoid
mylohyoid

Question 29

infrahyoid mm

Answer 29

thyrohyoid
omohyoid
sternohyoid
sternothyroid

Question 30

inn of digastric mm

Answer 30

ant: man nn (CN V3)
post: facial nn

Question 31

inn stylohyoid

Answer 31

facial nn

Question 32

inn mylohyoid

Answer 32

CN V3

Question 33

inn geniohyoid

Answer 33

nerve to geniohyoid

Question 34

chorda tympani hitches ride on what nn?

Answer 34

lingual branch of CN V3

Question 35

what Aa gives rise to the max Aa

Answer 35

ext carotid
