skin connective tissue aponeuresis loose areolar tissue pericranium
shearing injury of scalp happens between what layers
aponeuresis
loose areolar tissue
inferior areola ( dental nerve ) supplies where
lower dentation
farmer( serious) infraorbital nerve damage - what sx if tumour invades
numbness an apian in the Chee
branch of maxillary
pterygoid palatine fossa - if you don’t know guess this - behind jaw - where can a tumour spread from here
middel cranial fossa nasal cavity, oral cavity, orbit

branch of mandibular
brainstem does taste go too
nucleus solitarius - tasty
middle ear infection relevance is chorda tympani goes across your ear drum
bleeding skin cancer
how can you tell if underlying bone
SCC
does the scc move or not
if free moving skin graft if not chemo
2 areas of brain involved in pain perception
limbic system
thalamus
soamtosenosry cortex
pudendal nerve pathway
through greater sciatic foramen , round ischial spine and back into lesser sciatic foramen and then through pudendal canal
how does infection spread from the ear to cause thrombosis in the sigmoid sinus
emissary veins to mastoid process very close relation with sigmoid sinus
rare complication of Ottis media due to abx
small bone that contains semicircular canals
bony labrythn - fluid contained inside- perilymph
meningitis - inner ear infect causing labrynthtiis - delayed hearing loss
endolymph found in membranous labyrinth inside the bony bit - moves around with movement and hair cells sorted
scala vestiboli on top of scale tympani
scala media in the middle for you
cochlea nerve comes out the side
cochlea implant goes into what channel
scale tympani
top of tympanic membrane called
Bottom
pars flaccida - floppy - made of 2 layers
pars tensa - tense - made of 3 layers
cholesterol - negative Pressure in middle ear - sucks pars flaccida up into middle ear
form which pharyngeal arch are hillocks 1-3
and 4-6 derived
nerves supplying outer ear
Arch 1
arch 2
ant peripheral ear - auricular temporal nerve
post periterai ear - C2 - greater auricular nerve
cleft lift from what arch
1st arch
semicircular canals detect
angular movement
utricle and succulent detect linear movement - up and down
true
hippocampus
hippo = seahorse in greek
headache after vaccine ;eating to wopaltelt count and headache where could be blocked
venous sinus thrombosis - transverse sinus
dorsal colomns - vasiculus
vasiculus graiclis - legs
lateral ventricles to 3rd ventricle connected by
foramina of munro
dilation of ventricular system - meningitis
loss of reflexes
patient has spasticity, hyperflexxia in right leg - compression of which tract account fro this
UMN
lateral corticospinal tract
tentorium cerebelli - if ICP is raised abc this trucutre what cranial nerve will be damaged
oculomotor nerve
foramen magnum raised ICP what happen
coning
what nerves pass through the posoa muscle
lumbar plexus
horners sydrome often occurs with klumkes palsy
true
