paralyzed face
which cranial n has two parts? what are they
cn 11
cranial
spinal
what does cranial supply
PLES pharynx larynx esophagus soft palate
what does spinal supply
SCM
traps
what is spinal made up of (which cervical rami)
C1-c4
cervical ventral rami
What type of joint is the TMJ
modified hinge joint
What is the BS of the TMJ
inferior alveolar n
What is the NS of the TMJ
inferior alveolar a
inferior aleveloar n is a branch of which greater nerve
which in return belongs to which CN?
maxillary n CN5
inf alveolar a is a branch of which greater a
which belongs to?
maxillary a
external common carotid
what does the TMJ articulate with
mandibular condyle
mandibular fossa of temporal bone

fibrocartliage
what are the three ligaments of the TMJ
stylomandibular
sphenomandibluar
tempomandibular
FN of stylomandibular
pulls jaw backwards
FN of sphenomandibular
pulls jaw backwards
FN of tempromandibular
pulls jaw forward
four muscles of mastication (CN V3 or CN 5 aka only motor part of CN5)
massater
temporalis
lateral pterygoid
medial pterygoid
FN of massater
protrusion of jaw
jaw elevation
OI of massater
O: zygomatic bone
I: angle and rams of mandible
FN of temporalis
retrustion of jaw
elevation
OI of temporalis
O: temporalis fossa of frontal, parietal, and temporal bones
I: coronoid process of mandible
FN of lateral pterygoid
most power protruder
OI of lateral pterygoid
O: pterygoid plates
I: close to condyle
Waz special bout da lateral pterygoid
muscles run horizontally SO not much strength do elevation
FN of medial pterygoid
protrusion + elevation of jaw
which muscles do elevation
temporalis
medial pterygoid
massater
which muscles do protrustion
medial ptery
lat ptery
massater
which muscles do retraction
temporalis
which do depression
none (platysma does BUT not part of the TMJ) so…gravity in this case
what do facial veins NOT have?
VALVES!
weigh-whoooo
goodluck
