Neurological examination Flashcards
common components of neural exam
patient history, cranial nerve function, motor function, somatosensory function, coordination, mental status.
why understand handedness
lateralization
(left-handers can have crossed or mixed specialization for language - typically left hemisphere for right-handed)
disease process components
temporal profile, change over time, triggers/relievers, severity.
Cranial nerves
myelinated axons (white matter); can be afferent or efferent.
Cranial nerve I
Olfactory; sensory; smell information
Cranial nerve II
Optic; sensory; visual information
Oculomotor nerves
III, IV, VI
Cranial nerve III
Oculomotor; motor; 4/6 muscles that move eyes + eyelid movement
Cranial nerve IV (smallest)
Trochlear; motor; eye movement (only of trochlear muscle)
Cranial nerve V
Trigeminal; both motor and sensory; separates into 3 branches; facial sensation + biting, chewing, swallowing
Cranial nerve VI
Abducens; motor; eye movement (only of abducens muscle)
Cranial nerve VII
Facial; both sensory and motor; main motor output to facial expression + taste
Cranial nerve VIII
Auditory; sensory; hearing and vestibular sense (balance)
Cranial nerve IX
Glossopharyngeal;both motor and sensory; back of tongue taste + ability to speak and swallow
Cranial nerve X
Vagus; both motor and sensory; motor control of heart, lungs, viscera
