parasympathetic function: salivation, lacrimation
VII facial
26
parasympathetic function: salivation via parotid
IX glossopharyngeal
27
parasympathetic function: visceral function, heart rate
vagus
28
innervates the superior oblique muscle of the eye
IV trochlear
29
innervates the lateral rectus muscle of the eye
VI abducens
30
innervates the levator palpebrae muscle to lift eyelid
III occulomotor
31
the motor neurons of CN III, IV, VI are located in the [...]
III, IV are in midbrain VI is in the pons
32
unilateral damage to any of the three CNs controlling extraoccular muscles will result in
diplopia
33
what CN is damaged in this picture?
III occulomotor Note: mydriasis and manually lifting eyelid
34
damage to [...] results in the inability to move the eye out laterally
VI abducens
35
damage results in inability to shrug shoulder and turn head
XI spinal accessory
36
the motor neurons for spinal accessory are located [...]
in the spinal cord (C1-5)
37
damage results in abnormal tongue protrusion
CN XII
38
motor neurons for CN XII are located in the [...] nucleus
hypoglossal
39
most likely to be damaged by loss of blood supply to the midline of the brainstem [4]
CN III, IV, VI, and XII **live along the midline**
40
damage to [...] causes facial numbness and difficulty chewing
CN V
41
sensory function of CN V
somatic sensation of the face
42
innervates muscles of mastication, tensor palati, and tensor tympani
CN V
43
sensory nerves of CN VII synapse in the [...] nucleus [2]
spinal trigeminal solitary
44
innervates the muscles of facial expression and stapedius
CN VII
45
parasympathetic function: innervates the salivary, lacrimal, and nasal glands
CN VII
46
damage causes loss of taste, facial paralysis, and parasympathetic dysfunction
CN VII
47
[...] ganglion of CN VII innervates the lacrimal gland
sphenopalatine ganglion
48
[...] ganglion of CN VII innervates the submandibular gland
submandibular ganglion
49
the cell bodies of the nerve providing parasympathetic function of CN VII originate in the
superior salivatory nucleus (pons)
50
damage causes loss of taste and gag reflex
CN IX glossopharyngeal
51
innervates touch and taste to the back of the tongue
CN IX glosspharyngeal
52
innervates stylopharyngeous muscle
CN IX
53
innervates parotid gland
CN IX
54
sensory nerves of CN IX and CN X synapse in the [...] nucleus
spinal nucleus or gustatory nucleus (pons)
55
damage causes diminished gag reflex, hoarseness, difficulty swallowing
CN X vagus
56
innervates most muscles of the larynx, pharynx, palate
CN X vagus
57
gives parasympathetic innervation to viscera in thorax and abdomen
CN X vagus
58
the motor neurons from CN X originate from the [...] nucleus
nucleus ambiguus
59
parasympathetic neurons from CNX originate from [...] nucleus
dorsal motor
60
sensory neurons from CNX synapse from [...] nucleus
gustatory or spinal trigeminal
61
sensory function: mostly visceral afferents and taste at base of tongue
CN X
62
describe parasympathetic innervation of the ciliary muscle and pupillary constrictor via CN III
edinger-westphal nucleus --> CN III --> ciliary ganglion
63
CN most likely to be injured due to head trauma
CN IV
64
damage to CN IV affects the [...] eye
ipsilateral
65
damage to [...] results in head tilt to opposite shoulder to align the two visual axes
CN IV trochlear
66
damage to [...] results in failure to abduct the affected eye
CN VI
67
afferent limb of the gag reflex
CN IX
68
efferent limb of the gag reflex
CN X
69
damage to [...] results in ipsilateral eye pointing down and out, likely with a blown pupil
CN III occulomotor
70
because the facial motor neurons that innervate the forehead have bilateral corticobulbar innervation, strokes in the motor cortex will only affect the [...] face
lower
71
hallmark of a brainstem lesion
loss of sensation or paralysis on one side of the body accompanied by a cranial nerve loss
72
provides both taste and touch information about the posterior 1/3 of the tongue
CN IX glossopharyngeal
73
carries sensation to the anterior 2/3 of the tongue
CN V
74
innervates the intrinsic muscles of the tongue
CN XII
75
the olfactory nerves can be sheared off as they enter the [...] as a result of head injury
cribriform plate
76
CN associated with the midbrain [2]
