Formative Review Flashcards
Facial nerve route
Starts in pons, travels through internal acoustic meatus, geniculate ganglion, greater Petrosal nerve leaves
Patient can cry but not taste, where is facial nerve lesion
Middle ear- greater Petrosal nerve is in tact as parasympathetic function remains
just before it gives off chorda tympani and nerve to stapedius
Difficulty speaking and weak right arm, stroke is where
Left frontal lobe
Transient monocular blindness due to TIA blocking central retinal artery, where does this blood vessel arise
Opthalmic artery (which is branch of ICA)
Patient with lung cancer with sympathetic involvement facial inspection
Incomplete ptosis of right eyelid and constricted pupil
Unopposed parasympathetic innervation of sphincter pupillae
Otosclerosis right ear findings on examination
Webers: lateralised to right ear
Rinne’s: BC greater than AC
Branch of facial nerve responsible for taste
Chorda tympani
Any lump which moves when you stick out tongue in
Thyroglossal duct cyst
Order of treatment in epistaxis
Pinch, cautery, AP, PP
Most likely origin of infection in right eye
Ethmoidal sinus- medial wall of orbit is very thin
Squamous cell carcinoma on lower lip could spread to what lymph node
Submental
Pupillary light reflex
Light detected by photoreceptors in retina, optic nerve, pre rectal nucleus in midbrain, edinger wesphal nucleus in brainstem, parasympathetic fibres carried on oculomotor nerve, target tissue Is sphincter pupillae muscle
Optic nerve lesion is found
On same side as eye that does not react (already crossed at chiasm)
From which artery do the branches in the middle of the optic disc arise
Central retinal artery supplies retinal arteries, runs in the middle of optic nerve
Function of macula
Provides high acuity vision, point of retina for central vision
A = uvula
B = anterior pillar of palatoglossal fold/arch
C = Posterior pillar of palatopharyngeal fold/arch
D = palatine tonsil
