OMM 1 Flashcards
TMJ dysfunction symptoms
pain, clicking when mouth is open or closed, HA, sinus congestion, dizziness, facial pain, tinnitus, hoarseness, ear pain
Digastric and suprahyoid
depresses mandible
Depression/opening of the jaw ->
depresses mandible
Unilateral contraction of pterygoids
contralateral deviation and anterior
Contralateral pterygoids
draw articular disc anteriorly to facilitate opening
Direct blow to a closed mouth or WHIPLASH
posterior capsule injury
Malocclusion Class 2
overbite
Malocclusion Class 3
underbite
Upper molar extraction
temporal bone compressed into occiput
Lower molar extraction
temporal bone compressed into TMJ -> strained sphenomandibular joint -> sphenoid pulled inferiorly and contralaterally
Internal rotation of temporal bone
anterior lateral movement of mandible
External rotation of temporal bone
posterior and medial movement of mandible
Mandible deviates away from _______ rotated mandible
internally
Mandible deviates toward ______ rotated mandible
externally
Stylomandibular ligament
attaches temporal to mandible
Short leg ->
unleveling of occiput -> temporal and TMJ dysfunction
Flexion head
external rotation of paired bones (wide, flat)
Extension head
internal rotation of paired bones (long, narrow)
CNV1 may be affected by dysfunction of
Dysfunction of temporal bone
CNV2 may be affected by dysfunction of
temporals, sphenoid, maxillae and mandible
CNV3 may be affected by dysfunction of
sphenoid bone
CNV1 dysfunction may affect what
ethmoid sinus
Tic doulourex
CNV2 dysfunction
Trigeminal neuralgia
CNV3 dysfunction
External carotid may be affected by dysfunction of
temporal, occipital, sphenoid
Internal carotid may be affected by dysfunction of
cervical dysfunction C6-C2
Internal jugular may be affected by dysfunction of
temporal
Lymphatics to head may be affected by dysfunction of
upper thoracic spine, upper ribs (1-4), and clavicle
External carotid dysfunction may cause
weakness and altered sensation on opposite side
Internal carotid dysfunction may cause
vision abnormalities, and dizziness
Internal jugular dysfunction may cause
head congestion
Which n passes through the pterygopalatine fossa
CNV2
Abducens n lies under the
petrosphenoidal ligament
Entrapment of CN VI can lead to
strabismus and diplopia or sixth nerve palsy
Abducens n may be affected by dysfunction of
Sphenoid or temporal dysfunction
Bell’s Palsy
dysfunction of temporal bone impinging on facial n
parasympathetics to the eye are carried by
CNIII
parasympathetics to the lacrimal gland and nasopharyngeal mucosa are carried by
CNVII
CNVII parasympathetic hyperactivity ->
thin, watery secretions, excessive tear production
Somatic dysfunction at T1-T4 may cause
photophobia, tinnitus and unsteadiness, vasoconstriction
Hearing decrease and vertigo may result from dysfunction of __________ impinging on CN8
sphenoid, occiput and temporal bones
HEENT Chapman’s Reflex Points - anterior
clavicle to 2nd rib
HEENT Chapman’s Reflex Points - posterior
suboccipital musculature, intertransverse spaces C1-C2
All facial bones except mandible are driven by
sphenoid
Referred sinus pain follows
trigeminal
CNV1 innervates all sinuses except
Maxillary (CNV2)
Otitis Media may be caused by ______________ of the temporal bone
internal rotation
secretory to submandibular, sublingual and lacrimals
CNVII
Parasympathetic n carried by CNVII
Greater Petrosal
Parasympathetics carried by glossopharyngeal synapse ____________ and innervate
otic ganglion; parotid gland
Sympathetics to the head are carried via
T1-T4 -> sphenopalatine ganglion
Vertigo may result from dysfunction of
temporal bone
Internal rotation of the temporal bone
closes off the ET; high pitched ringing
