Which nerves control the eye movement? How to test
3, 4, and 6. Move finger in the H shape and then move close to face to test accommodation
74
Test ipsilateral and consensual pupillary light reflex
Ipsilateral - Ask subject to look at distant target. Shine one eye with penlight, observe pupillary constriction in the same eye. Consensual - Ask subject to look at distant target. Shine one eye with penlight, observe pupillary constriction in the fellow eye. Swinging torch – RAPD – both pupils constrict when light swings to undamaged side, both pupils paradoxically dilate when light swings to damaged side.
75
What direction do CN III, IV and VI move the eye
III - adduction (towards middle) and up IV - adduct and down VI - abduction
76
Afferent pathway of the accommodation reflex? (7)
Afferent from the primary visual pathway: retina -> optic nerve (CN2) -> optic chiasm -> optic tract -> lateral geniculate body -> optic radiation -> visual cortex.
77
Efferent pathway of the accommodation reflex?
visual cortex -> pretectal nuclei -> Edinger-Westphal nucleus -> CN3 -> sphincter pupillae.
78
What muscle and nerve controls the pupil?
Sphincter pupillae, CNIII
79
Afferent and efferent arms of the corneal reflex?
Afferent – nasociliary branch of ophthalmic branch of trigeminal (V1) Efferent – temporal and zygomatic branches of facial nerve (VII)
80
Test the sensory functions of the three divisions of the trigeminal
Trigeminal is the sensory nerve of the face To the eyelids is the ophthalmic Anterior temple, middle part of the face to the corners of the mouth is the maxillary Middle part of the temple anterior to the ear and down to the chin is the mandibular branch, as is the lower teeth, gums, lips, inside of cheeks, floor of mouth and anterior 2/3rds of the tongue
81
Test the motor function of the accessory nerve
Shrug shoulders to move trapezium and turn head to test SCM
82
Test the motor function of the mandibular division of the trigeminal nerve
Palpate masseter (cheeks) and temporalis (temples) muscles
83
Test motor function of the facial nerve
Ask patient to adopt various expressions and look for assymetry - smile, frown, close eyes tightly, lift eyes, show teeth, puff cheeks.
84
What are the functions of the facial nerve
Supplies motor muscles of facial expression & via chorda tympani, parasympathetic to submandibular/sublingual salivary glands
85
Test function of the glossopharyngeal nerve
Use 2 tongue depressors (1 to hold tongue down and other to touch back of mouth) and evoke a gag reflex. It is the sensory nerve of the posterior 1/3rd of the tongue and oropharynx
86
Test motor function of the vagus
Ask the subject to open their mouth and say “ahh” and observe the elevation of the uvula to see if there is any deviation from the midline (away from the lesioned side)
87
Test the motor function of the hypoglossal nerve
Protract (stick out tongue) deviation goes towards lesioned side
88
What is the motor function of the hypoglossus
The tongue
