Cranial Nerve Considerations Flashcards
1
Q
olfactory (1)
A
rarely involved, typically skipped
2
Q
optic (2)
A
- field cuts/visual loss
- reduced visual acuity (blurry vision)
3
Q
oculomotor, trochlear, abducens (3,4,6)
A
- gaze palsies –> double vision (diplopia)
- ptosis
4
Q
trigeminal (5)
A
- loss of facial sensory input
- asymmetrical jaw movement and strength
- loss of mastication –> choking risk –> aspiration risk
5
Q
facial (7)
A
- facial weakness, loss of sensory of the tongue, impairment of salivary glands –> choking risk –> aspiration risk
- impairment of lacrimal glands n–> impaired vision
6
Q
vestibulocochlear (8)
A
- hearing loss
- vestibular dysfunction –> vertigo, balance deficits
7
Q
glossopharyngeal (9)
A
- dysphagia
- reduced taste and sensation on tongue, loss of gag reflex –> choking risk –> aspiration risk
- ANS: CV dysfunction (HR, BP)
8
Q
vagus (10)
A
- pharyngeal and laryngeal weakness
- loss of gag reflex –> choking risk –> aspiration risk
- ANS: abnormalities of esophageal motility, gastric acid secretion, gallbladder emptying, CV dysfunction (HR)
9
Q
spinal accessory (11)
A
UT and SCM weakness –> inability to rotate head or shrug shoulders
10
Q
hypoglossal (12)
A
tongue weakness –> choking risk –> aspiration risk
